github: bump versions of various actions

Bumps:

 * Update actions/checkout, actions/setup-go,
   golangci/golangci-lint-action from v2 to v3.

 * Bump golangci-lint to v1.45.

Cleanups:

 * Remove "stable" parameter for setup-go (not needed since v3,
   see [1]).

 * Remove the obsoleted comment for golangci-lint (no longer
   true, see [2]).
