Support upgrading version in bzlmod single_version_override

[honnix]

Tell us more.

#22610 added the feature supporting single_version_override, however there is no way to allow renovate to update version specified in single_version_override. While it is understandable users might intend to pin that version, in practice it is not always true. For example, when patching MODULE.bazel itself, it is often necessary to specify a version in single_version_override, but it does not necessarily mean users don't want to get version bump, as long as a new version doesn't invalidate the patch file (if it does bazel would fail immediately anyway).

I think it makes sense to add a config to enable version bump in this case.

I can no longer comment on #22610, but it seems if single_version_override has neither version or registry, the dep would still be ignored. Not entirely sure, but if so, it is not a correct assumption.

NVM this is not true.

@honnix is this a feature you'd interested in adding yourself? If so then you could start right away. If not then I'd ask for a reproduction repo + example PR so that we can convert this to an issue

[honnix]

@rarkins I don't think I know enough to get this fixed, especially around how to add a config to overwrite the behaviour. Do you think this feature request needs a repro? It's not a bug but designed in this way as the documentation says.

[rarkins]

The reason for a reproduction repo is so that we can test against a real repo. It's good practice to test against a real repo for both features and fixes

[honnix]

I see. That makes sense. I will put up a repo and share it back here.
