Versioned GitHub repository links from our docs

[emilk]

We link to files on GitHub quite often in our docs.

For instance, we link to https://github.com/rerun-io/rerun/blob/main/examples/python/log_file/main.py
The problem is that that file is gone.
We should have linked to https://github.com/rerun-io/rerun/blob/0.15.0/examples/python/log_file/main.py instead

So how do we solve this?

Unclear

• If we use /blob/main/ the file may change or disappear
• If we use /blob/latest/ the file may also change or disappear, and the CI may be green just before a release, but the link in the release is wrong
• If we hard-code tags in our links (/blob/0.15.0/) our docs will link to old code

Immediate problems for 0.16 release

(Fixed in #6331)

Just had a user run into errors when trying to run https://www.rerun.io/docs/howto/extend/extend-ui since they copied code from that link into their own project, and ended up using in-flux 0.16 APIs against the 0.15 release.

Everything that is mentioned in an examples/ README.md should actually be trivial to solve: just do relative paths. landing has to understand that ofc then
