fix(jsxref): fix dot handling

Previously we replaces all single dots with a slash.
This resulted in:
{{jsxref("Operators/new%2Etarget", "new.target")}}

An alternative is to change the logic to:

If there is an slash in the 1st parameter don't replace the dots.
This works for all en-US and the issue I found in translated content
where alread broken.
