Leverage `debug.BuildInfo` from go 1.18

[endorama]

Go 1.18 provides some built in information to retrieve VCS status from the binary via debug.BuildInfo

Quoting:

The runtime/debug.BuildInfo returned by runtime/debug.ReadBuildInfo() has been updated to include a new field Settings []debug.BuildSetting. Settings in turn are key-value pairs describing a binary. The commit hash is the value for the key vcs.revision, and vcs.time does what you would expect. There’s even vcs.modified to tell you if the build was “dirty” or “clean”.

An example implementation https://github.com/carlmjohnson/versioninfo

We should replace current implementation in version with debug.BuildSetting values.
