Do not explicitly specify uv version in calls to setup-uv

[Cadair]

I'm not entirely sure why these versions were here, I don't think we want to pin it, latest should be fine?

IMO it would be better to have reproducibility, since uv is still under active development and is not yet at 1.0.0 (just in case a new uv version breaks something)

[Cadair]

I kind of feel like if we can't trust latest release of uv then that's a good reason not to use it.

The motivation for this is trying to figure out why uv isn't installing the latest bugfix release of 3.14 e.g. here.

I think if we are going to pin this, I'd be nice to both have a reminder to update it, and also a way for users to override it.

[zacharyburnett]

that's a good point, I haven't seen a case where a uv update breaks existing CI, and setup-uv is being used in a lot of other projects without pinning the uv version, so it seems good to trust

Are you good with merging this and #397 and putting them both out as a 3.0?

Sure, but could we consider #392 as well if we're doing a major version bump?
