CI: update to the latest goreleaser version

It seems like our config is still valid,
as we aren't affected by anything recent outlined in
https://goreleaser.com/deprecations/ since v1.1.0.

I ran both v1.1.0 and v1.8.2 locally via

	goreleaser build --skip-validate

and on both versions the tool appears to work.
It seems safer to stick to the latest stable version.

internal/core/adt: fix matching of "_" label

The introduction of the wildcards in the API introduced
a regression that caused the string label "_" (which has
the feature label 0), to be incorrectly singled out.

The logic has now changed to reflect this. Note that without
the changed logic, TestAllow in cue/types_test.go will fail.

This also fixes printing of Selectors. Again, here "_" was
incorrectly singled out and would convert a string label to
a hidden label. This only seems to affect debug output.

This was currently only not allowed for imports.

Really import indices should be unique per context, but
