ci: remove workflow_dispatch inputs on check-go-version workflow (#313)

The "force create issue" on the check-go-version workflow was useful for
testing out the workflow even if the Go versions were up-to-date.

Since this files a PR now based on actual changes, the input doesn't
make sense to have.
