Bump the versions of Go used in Travis
Bump the versions of Go used in Travis to the latest point releases in
preparing for the upcoming v0.16.0 release.
Also switch the go download URL to the new go.dev domain.
Also update LANGUAGES.md accordingly, and mark that we support THeader
in Go now (we added the support in v0.13.0, just forgot to update
LANGUAGES.md accordingly).
