Browser Support Update

[Raymondo97]

For the positive and negative look behind options, the tool reports that there may not be support in all browsers. As of March 2023, it now has full support. So this warning can be removed. See attached link to Mozilla docs:

Here is a screenshot of the warning for reference:

Well if anything, it should be changed to "The 'positive lookbehind' feature may not be supported in all applications" or "in all algorithms".

There are two main classes Regex algorithms: one that uses NFA (nondeterministic finite automata), and one that uses backtracking. The NFA one does not support backtracking or "positive lookbehind", but runs in linear time. The on that uses backtracking has all the cool bells and whistles that NFA doesn't, but can run into a problem known as Regex DDoS, where the algorithm takes forever trying every possibility. Certain programs, like ripgrep, don't support backtracking (by default, some having settings to support it), so it'd probably be better to change the wording, rather than suggesting that it's supported by everything.
