feat(rules): add regex support for [subject|header]-full-stop rules

[sepehr]

Description

This allows usage of string regular expressions as value for subject-full-stop and header-full-stop rules.

Motivation and Context

We, internally, allow a range of stops. The current rule, however, allows providing one stop character which is restrictive, at least, in our use-case.

Yet, I'm not sure if it's a better fit for a plugin or the core.

Usage examples

// commitlint.config.js
module.exports = {
  rules: {
    'subject-full-stop': [2, 'always', '[\\.0-9]'],
    'header-full-stop': [2, 'always', '[\\.0-9]']
  }
};

# subject
echo "test: subject" | commitlint # fails
echo "test: subject." | commitlint # passes
echo "test: subject #42" | commitlint # passes
echo "test: subject #420" | commitlint # passes

# header
echo "header" | commitlint # fails
echo "header." | commitlint # passes
echo "header #42" | commitlint # passes
echo "header #420" | commitlint # passes

How Has This Been Tested?

By adding new test cases.

Awesome, I like this feature ❤️ @marionebl what do you think?

I think this completely got lost during busy times.
@sepehr if you are still motivated and willing to rebase and switch the files to typescript I think we could merge this.
It was already approved anyways...
Sorry for the long delay!

[sepehr]

Thanks for the update @escapedcat. Will surely do.

Since I got your attention, do you think #819 might also worth rebase and Typescript port?

[escapedcat]

Yeah, sounds good to me! @byCedric already commented positive on #819. Thanks for your effort!

@sepehr closing this for now. Please reopen if you find time for a rebase.
