docs: fix typo in HTTPRoute reference docs

[bezarsnba]

Correct a typo in linkerd.io content/2-edge/reference/httproute.md to improve documentation clarity and accuracy.

This change fixes a spelling error in the HTTPRoute reference page for the 2-edge docs, ensuring the Linkerd documentation remains professional and easy to understand.

Thanks for addressing this inconsistency. Upon review of the page, I see that it's not just httpPathModfier that's inconsistent, but all of the other names too: httpRouteRule, httpRouteMatch, httpPathMatch, httpHeaderMatch, etc.

Would you mind fixing all of them?

One other note, in your change in authorization-policy.md‎ the anchor link should always be lowercase. For example:

[HTTPPathModifier](#HTTPPathModifier) -> [HTTPPathModifier](#httppathmodifier)

Thanks for the feedback! I've addressed all the inconsistencies you mentioned:

✅ Fixed all section heading names to PascalCase for consistency:

• httpRouteRule → HTTPRouteRule
• httpRouteMatch → HTTPRouteMatch
• httpPathMatch → HTTPPathMatch
• httpHeaderMatch → HTTPHeaderMatch
• httpRouteFilter → HTTPRouteFilter
• httpHeaderFilter → HTTPHeaderFilter
• httpRequestRedirectFilter → HTTPRequestRedirectFilter
• httpBackendRef → HTTPBackendRef
• httpRouteTimeouts → HTTPRouteTimeouts
• And fixed the original typo: httpPathModfier → HTTPPathModifier

✅ Updated all cross-reference links to use correct capitalization while keeping anchor fragments in lowercase (e.g., [HTTPPathModifier](#httppathmodifier))

✅ Fixed anchor link in authorization-policy.md to use lowercase

All changes are ready for review!

Thanks for taking another look at this.

It appears that all of the names were updated correctly in the 2-edge version of reference/httproute.md (although I did not do an in-depth look yet), however, in all of the other versions, only HTTPPathModifier was fixed. Also in these other versions, there's an anchor link that's not lowercase ([HTTPPathModifier](#HTTPPathModifier))

Good catch, thanks! I've now applied the full standardization to all versions (2.13–2.19 and docs), not just 2-edge — headings in PascalCase, link texts updated, and all anchors lowercase. I also fixed the httpQueryParamMatch heading that was missed in 2-edge and standardized the embedded HTTPRoute section in 2.12/reference/authorization-policy.md. Ready for another review!

All of the casing looks good, and great catch finding the typo in HTTPPathModifier.

The only concern I have is changing the resources names from plural to singular. I completely understand why you made this change, since the plural form is not the accurate name of the resource. However, "A list of HTTPRouteMatch." doesn't read very well.

Elsewhere in the docs we have handled it like: A list of [HTTPRouteMatch](#httproutematch)es, which I also don't like very much, since terminating an anchor link in the middle of a word seems like a typo.

My preference would be to leave them plural (e.g.: [HTTPRouteMatches](#httproutematch)), since we commonly pluralize these resources names in the content, such as "HTTPRoutes". Or, append the word "resources" whenever we're referring to a list (e.g.: A list of [HTTPRouteMatch](#httproutematch) resources). Either one is fine with me.

If we append the word "resources", we should probably also run Prettier to clean up the markdown table whitespace.

I'm a fan of e.g. A list of [HTTPRouteMatch](#httproutematch) resources), thank you! And thanks for sticking with this one. 🙂

[bezarsnba]

Sounds good, thanks both! I went with A list of [...] resources across all versions (2.12-2.19, docs, 2-edge) and re-aligned the markdown table whitespace to match. Ready for another look.

[travisbeckham]

Thanks for taking the time polish this up @bezarsnba!

There's one instance that's still singular and needs "resources" appended: An array of [HTTPBackendRef](#httpbackendref) to declare... → An array of [HTTPBackendRef](#httpbackendref) resources to declare..., but after that, it looks good to merge.
