Fix monit version fact

[erik-frontify]

Pull Request (PR) description

Looks like monit version 6 has 3 digits to the version. At least on CentOS:

This is Monit version 6.0.0

So this PR adjusts the regex to still be able to see the current monit version

I can see why the test is failing. But the test looks for Amazon linux, that is not even configured in the params. So I'd say the test is wrong.

@erik-frontify thanks for the PR! Could you please rebase and add a unit test for the new format?

Hey @bastelfreak, I didn't change anything on the format. AFAICT the configuration didn't change from monit 5 to monit 6. It just failed to gather the current monit version. Which is weird, as the fact regex should've failed before the update, as it was 3 digits before: This is Monit version 5.33.0
But since the upgrade we had the error Evaluation Error: Error while evaluating a Function Call, start_delay requires at least Monit 5.0. Detected version is <0.0>.
On Redhat 9 it worked, on CentOS Stream 9 it failed. But both are os.family RedHat, so the version should've been set to 5 through params.pp.
Still, the PR fixes this, as now the right version is detected.

The failing test is wrong IMO, as there is no case for Amazon Linux any more. I can provide a PR for that, just didn't want to mess with your tests
