Fix for '/|/g can be optimized to //g' in the better-regex rule breaks regular expression syntax

[haykam821]

An empty regular expression such as // is invalid and parsed as a line comment instead, which breaks other syntax within the code. I would expect the better-regex rule to not propose code with empty regular expressions.

The following is a minimal example:

const expression = /|/;

I would expect this expression to be corrected to something like:

const expression = /(?:)/;
