x/website: some sub-repositories are missing from golang.org/pkg/#subrepo

[perillo]

The sub-repositories arch, lint, mod, oauth2, term, website and xerrors are missing from https://tip.golang.org/pkg/#subrepo.

They are also missing (with debug, perf, review and time) from https://godoc.org/-/subrepo.

This is intentional. That list is not exhaustive, it includes repos that are more noteworthy.

Commit golang/tools@370143d made it more clear that it was intentional, but that code has been factored into x/build/repos by now.

That said, we may want to consider including some of the newer repos, such as x/mod and x/xerrors.

I believe https://pkg.go.dev/golang.org/x is the canonical advertised list now.
