fix: treat .local domains as local (use HTTP instead of HTTPS)

[simonbaird]

Extend the reLocal regex to match *.local in addition to *.localhost, so that .local registries default to HTTP.

The Conforma CLI acceptance tests use a local registry that does not support TLS. Without this change, go-containerregistry attempts HTTPS connections to *.local registries, causing those tests to fail. We may add TLS to the acceptance-test cluster in the future, but for now let's do this to get the tests passing again.

See also commit 2d86301 where the regex was changed 8 weeks ago.
