chore: run cargo dev generate-all on CI and locally (#6899)

## Summary

Noticed that running `cargo dev generate-all` on `main` produced changes
and saw that that the command is not run on the CI nor as a pre-commit
hook.

Not sure if having the command running as a pre-commit hook is something
we want, so I can remove it if you prefer. I find that nice to have as
it's probably easy to forget to run it, especially for new contributors
(and it will only run if there are changes in `uv_cli` or `uv_settings`
crates).

## Test Plan

- Added `cargo dev generate-all --mode check` on the CI, which produced
[this failing
job](https://github.com/astral-sh/uv/actions/runs/10648055597/job/29516699393)
- Ran `cargo dev generate-all` locally and committed the changes, which
produced [this succeeding
job](https://github.com/astral-sh/uv/actions/runs/10648076910/job/29516744942)
