Add `tel:` when linking phone numbers

[jeryj]

What problem does this address?

When adding a link to email addresses, we automatically apply the mailto: for the link. It would be great to do this for telephone numbers too.

What is your proposed solution?

Follow the same route as https://github.com/WordPress/gutenberg/pull/14857. The biggest hurdle would be getting the regex for phone numbers.
