[repo] Bump rust version and dependencies

[EclecticGriffin]

I've bumped the rust version to 1.88 and also updated the versions of our rust dependencies. As this updates clippy, that means a bunch of new lints are active now, so I had to go and correct those as well. The vast majority are format string related.

Unfortunately that makes for a bit of a big PR.

I scanned through it, and it looks good. Basically mostly a number of format string changes.

Incidentally there is still a future incompatibility warning because morty hasn't been updated in several years and uses and old version of sv-parser which uses a version of nom that triggers the warning. Naturally there are later versions of sv-parser that don't do this but morty isn't using them. For now it's probably not an issue, but as the crate seems largely unmaintained at this point it may be necessary to take some action once it becomes a hard error.

Thanks for doing this, @EclecticGriffin! The string-templating changes, while sensible, are a bit of a slog. I'll go ahead and merge this now!

About the morty: unfortunately, this is such a useful dependency that it would be a shame to just try to remove it... maybe we should look to see if it is feasible to contribute a version bump?

I wasted a little bit of time looking into this and ended up opening pulp-platform/morty#65. However, along the way, I noticed that the git trunk for morty already has fresh enough dependencies—so I've opened #2535 to just depend on that instead of the released version.

Oh cool! Glad it was easy to resolve. Was worried we'd have to make a fork and bump a ton of dependencies ourself
