6.5.0 documentation is starting to wither away

[grepwood]

Page link:

https://bazel.build/versions/6.5.0/rules/lib/builtins/repository_ctx

Problem description (include actual vs expected text, if applicable):

It should not be 404. There are still people who have barely migrated from 5.x.x.

Where do you see this issue? (include link to specific section of the page, if applicable)

On the specified link

Any other information you'd like to share?

Please stop pre-emptively burning the documentation for older releases.

The old page is actually still there (https://bazel.build/versions/6.5.0/rules/lib/repository_ctx -- note the missing builtins segment between lib and repository_ctx); the new version selector makes it go to the "imaginary" new URL.

I wonder if this is as simple as fixing the set_var clause in the 6.5.0 pages? Also need to figure out why the navbar on the left is empty.

Yeah, for older docs, please start navigating from https://bazel.build/versions/6.5.0

There are two problems:

1. Because of 6dbac49 the generated Starlark docs prior to 7.x have a different layout. The only solution is adding redirects.

2. Between 6.2 and 6.3 the left navbar disappeared: https://bazel.build/versions/6.2.0/reference/be/overview vs https://bazel.build/versions/6.3.0/reference/be/overview

[fweikert]

Both of the aforementioned issues have been fixed.

There is still a problem, though: Whenever we introduce new Starlark symbols, the version selector will lead to 404 errors when switching to versions that don't contain these symbols yet. I guess we need to set up another bunch of redirects when 8.0 comes out.
