Make URL scheme unambiguous

[ethantkoenig]

Fixes #2364. Modifies URL schemes to remove ambiguity (see #2364 (comment))

The GET /:owner/:repo/src/* endpoint becomes three endpoints:

• GET /:owner/:repo/src/branch/*
• GET /:owner/:repo/src/tag/*
• GET /:owner/:repo/src/commit/*

Similarly for GET /:owner/:repo/raw/* and GET /:owner/:repo/commits/*. The old routes are redirected to the new routes to maintain backward compatibility.

Is it possible to migrate links from older comments to the new URL scheme to avoid dead links?

[ethantkoenig]

@JonasFranzDEV I think a better solution to dead links is to have old links redirect to their new counterparts. I'll work on adding redirects soon.

~~~Add a paragraph inside swagger comment starting with "Deprecated:"~~~

[ethantkoenig]

@sapk Isn't swagger just for API endpoints?

[lunny]

Yes. I think swagger only for API? This PR's break links is for UI.

[sapk]

@lunny @ethantkoenig sorry misread ...

[ethantkoenig]

@JonasFranzDEV @sapk Added redirects from old URL scheme to new scheme

[lunny]

cannot switch to another branch on the menus.

[ethantkoenig]

@lunny Will take a look by Sunday at latest

[ethantkoenig]

@lunny Fixed. There were actually two problems:

1. The branch dropdown template used the old URL scheme
2. The redirect to the new URL scheme did not work

Both problems are fixed

[ethantkoenig]

Rebasing to re-run CI (passes locally)
