add ref to regex pattern that matches proc signature for formatting

[arezaii]

This PR adds pattern matching for proc ref name(args) where previously
the ref this intent would cause sphinx to not format the proc the
same as others, and also not generate a permalink for the signature.

TESTING:

• hyperlink and correct format for signatures with ref this intent
• dif the new docs with the old docs
