misc: disable G601 lint rule

This rule is no longer relevant to Go 1.22+, however golangci-lint is
still using an older version of gosec which does not yet include the
changes to disable this warning on this version of Go.

The changes to update gosec have been merged, but are not yet included
in the latest version of golangci-lint (to the best of my knowledge,
given the linter is still complaining about it, and the milestone for
that PR is 'next' at the time of writing this): golangci/golangci-lint#4724
