Provide links to message about stylelint

@StanislavSapogov Perhaps, will #7484 resolve your problem?

[Mouvedia]

What type of link are you talking about?
An anchor link pointing to the core rule itself?
A string argument which would be added to every rules?
What's your use case? Why do you need that url?

[StanislavSapogov]

We have documentation for our design system and I'm writing a rule to help our developers use our variables, so I'd like to provide a URL to our docs :)
So, it would be possible to see them in hovers in vscode e.g.

'declaration-property-value-allowed-list': [
      {
        '/^font-weight/': [
          'var(--design-system-regular)',
          'var(--design-system-medium)',
          'var(--design-system-semi-bold)',
          'var(--design-system-bold)',
        ]
      },
      {
        message:
          'Consider using design tokens instead https://read-the-manual.please',
      },
],
