cmd/gorelease: allow -base to be a different major version

gorelease already allows comparing different modules, and major
versions are technically distinct modules, but it's inconvenient to
write the full module path with -base on the command line.

With this change, for example, when checking example.com/mod/v2, the
user can now write -base=v1.9.0 instead of -base=example.com/mod@v1.9.0.

Fixes golang/go#40913

PkgGoDev

This subrepository holds experimental and deprecated (in the old directory) packages.

The idea for this subrepository originated as the pkg/exp directory of the main repository, but its presence there made it unavailable to users of the binary downloads of the Go installation. The subrepository has therefore been created to make it possible to go get these packages.

Warning: Packages here are experimental and unreliable. Some may one day be promoted to the main repository or other subrepository, or they may be modified arbitrarily or even disappear altogether.

In short, code in this subrepository is not subject to the Go 1 compatibility promise. (No subrepo is, but the promise is even more likely to be violated by go.exp than the others.)

Caveat emptor.
