Contributor credit (CITATION.cff)

I lied about us having a CITATION.cff file. I was looking at the deno validator.

I looked at the most recent legacy-validator release (v1.14.6) that had Python in it, and here's the shortlog of the Python files only.

If we want to count the regular expression data files, it's a much more significant list:

I think my position is probably: If someone's contributed to the Python components of the validator specifically, they should be opt-out. If they only contributed regex rules, I would make it opt-in, as most of them probably considered themselves to be contributing to the Javascript validator, and the regex rules have been removed (except as data files).

@rwblair @ubdbra001 Does this sound fair to you?
