Fix goreleaser dirty state check for CI dashboard build

The release workflow builds the dashboard before goreleaser runs,
which produces new content-hash asset filenames and leaves the tree
dirty. Use --skip=validate (goreleaser's documented fix for this) and
remove the invalid git.dirty_ignore field added in the previous commit.
