Imply not using cache when invoking sync --update-all

Hi! This is an attempt to fix #1128 by basically passing the --no-cache to uv command on lockfile generation.
This should work exactly the same (https://github.com/astral-sh/uv/blob/8ae5c2aee3fa22ac7d11337688e4c1bee3748fe3/crates/uv-cache/src/cli.rs#L17) as adding UV_NO_CACHE=true as environment variable as the issue author tried in order to get the desired behaviour.

Interesting. Thanks for putting up a fix. You should be able to use --refresh instead of --no-cache, the latter will disable writes to the cache as well which is overkill. Not entirely sure if there's a better approach than that though without looking into the original issue further.

I'm still a bit confused about why this is necessary though.

Got you, no problem. The use-case is described in the issue, so I thought that made sense

But if there's a new release, uv should upgrade to it without refreshing — unless it's been released in the last 10 minutes (which is the TTL for cache of the available releases). It might make more sense to just expose the --refresh flag in Rye. I think we'll need a clearer picture of the problem before it makes sense to change the uv invocation.
