go_deps should expose resolved versions for all Go modules it Bazelizes, for external bookkeeping

[Buzz-Lightyear]

What version of gazelle are you using?

v0.38.0

What version of rules_go are you using?

v0.49.0

What version of Bazel are you using?

7.1.2

Does this issue reproduce with the latest releases of all the above?

Yes

What operating system and processor architecture are you using?

macOS Sonoma 14.5, arm64 (Apple M1 Max)

This isn't a bug but a feature request. I'd like the go_deps module extension to expose the mapping between every Go module it bazelizes and its resolved version. This would be extremely useful for external bookkeeping (for e.g. we can easily communicate to CI systems that rely on native package manager metadata, precisely what version of each Go module was used in the build).

I'll shortly create a sample PR demonstrating what we might need although I'm not claiming that it would the optimal mechanism to surface this data.
