[CI] Fix benchmark triggers

[rengolin]

This fixes both workflow_dispatch, now with check-boxes instead of integers and actually running correctly, as well as pull_request that now doesn't need to remove/add the benchmark label every time you update the PR.

Ok, PR updated after adding the label and I did not need to remove/add to re-run the benchmarks. Seems to be working.

What's the new behavior? Does it dispatch benchmarks on all PRs automatically or only after labeling but without the need to reapply label afterwards?

It always dispatches the benchmarks on every PR, but they don't run of the label is not there, so they show as "skipped".

Once applied, the label will trigger the check and when the benchmarks run again on update, the check will succeed and they won't be skipped.

the only problem now is that any update on a PR will run the benchmarks. I'm trying to find the right set of actions that will only update on rebase / reopen / label. but at least comments don't trigger, only updating the title/description, so not critical now and better than before.

Looks fine, let's take it for a spin and see how it goes in practice
