WPP-11685-updated PR workflow

[faridahsalami-nhs]

Summary

This pull request introduces changes to the PR Quality Check GitHub Actions workflow (pr-lint.yaml) to enable it to post a comment on the PR with a link a WPP Jira Ticket, when one is included in the branch name from which the PR is created. This type of feature existed previously in this workflow but it didn't work for tickets with out current WPP Jira prefix. These changes also remove the ability for no-longer-used Jira ticket prefixes, such as APM and AMP, to trigger the creation of a comment.

Additional changes:

• added functionality for workflow to comment on a PR with instructions on what to do when when a PR has been raised from a branch which does not have a valid Jira ticket number in the branch name. After the comment is posted the workflow fails.
• The Check ticket name conforms to requirements step has been refactored to use built-in bash commands rather than grep, as pattern matching can be achieved without spawning a subprocess to run grep, which is slightly more efficient.

Unchanged:

• branches starting dependabot/ are still valid and will not cause the PR Quality Check to fail.

TESTING:

• This workflow has been tested on this branch and the relevant Jira ticket comment with link can be seen posted, on July 23rd at 16:32, lower down this page.
• The unhappy path, where a warning message is posted, has been tested via draft PR add alternate pr-lint workflow #170. That PR will be closed once this one has been merged. Please check that comment's content and styling while reviewing this PR.

Looks good to me, can see it working in both happy and sad paths.
Is there corss-over with Utilities we could make use of to ?

as mentioned in teams - this might replicate some of the existing checks done in the reusable actions myself and @chetan-nhs-acn have been working on and the existing RAA ones, can you take a look at the actions we have just to ensure we aren't duplicating anything, particarly the branch and PR title validation
