bug#61238: [PATCH] Fix go-ts-mode type switch and select case blocks indentation

[Theodor Thornhill]

Hey there, Davide, and thanks for the clear bug-report!

This looks good to me, but before I install, Maybe you can also add a
test for this, similar to the ones in c-ts-mode-tests.el?

Also, just checking - is fsf assignment needed for this change? Maybe
you've done it already, if so, forgive my ignorance :-)
