Subject: [PATCH] languages: Fix semantic tokens for Go (#51621)

Closes #51620

gopls requires more specific initialization for semantic tokens that
other language-servers for reasons that aren't entirely clear to me, it
is however a small fix to make it work. still trying to track down other
malfunctioning language servers in the semantic token realm, so if you
have suggestions let me know.

original behavior (on nightly v0.229):
