Replace GitHub API version checks with redirect-based lookups to avoid rate limits

[marco-carvalho]

What has changed?

Replaced GitHub REST API calls (api.github.com) with redirect-based version lookups using the /releases/latest page URL to avoid the 60 requests/hour unauthenticated rate limit.

• Added a shared getLatestGitHubReleaseTag utility in src/utilities.ts that extracts the version tag from the GitHub releases redirect URL.
• Replaced getLatestVersion and getLatestNightlyVersion in src/lsp/client/downloader.ts with calls to the shared utility.
• Replaced the API-based getLatestVersion in src/nrepl/deps-clj.ts with a call to the same shared utility.

Fixes #3142

Thanks! Makes total sense. Right now it doesn't build, though. Not sure you've seen? https://app.circleci.com/pipelines/github/BetterThanTomorrow/calva/9788/workflows/6e54127a-8060-499b-806e-ccd9995ea9d7/jobs/59810

@PEZ sorry, fixed!

[marco-carvalho]

@PEZ good morning! if you would be so kind, could you review again, please?
I still don't know why, but sometimes I'm hitting this annoying rate limit 😅

Thanks!!!
