Subject: [PATCH] Always point to versioned manifest when building a versioned
 binary (#4781)

### What
 - Resolves: https://github.com/rerun-io/rerun/issues/4778

The logic here is that if you check out 0.12.0 and do a source build you
probably want the 0.12.0 examples, not the example from main. This is
generally what folks will want if integrating a rerun-build into a
third-party system, and similarly applies to conda.
