misc: small additions to logging; bump `git2` and `rust-version` versions

[n-dusan]

• Fix url resolution by cleaning the trailing / from the request
• Add more tracing spans to app, and add debug tracing to versions endpoint;
• Upgrade git2 version to 0.18. This solves a CVE issue found in libgit2;
• Bump rust-version to 1.78;
• Bump all other dependencies using cargo update

Yes. Does this current tracing span look reasonable?

It looks great! I imagine that kind of stuff can be hooked into things like https://sentry.io, or at least I mean it can help you do some powerful debugging.

And I guess you could probably add your own data to it, say the user ID or something.

Agreed. I don't know much about how sentry works, but centralized logging has been on my mind for a while now. I'll have some talks to see whether we can get that onto our stelae roadmap.
