Allow URLs in developer replies to ratings

[diox]

Fixes mozilla/addons#15069

Can you add some testing steps?

[diox]

1. Log in as a regular user
2. Try posting a rating with an URL - it shouldn't work.
3. Post a rating on an add-on
4. Log in as a developer of that add-on
5. Post a reply to the rating posted earlier with an URL - it should work.

Looks good. FWIW I could add www.google.com but not https://www.google.com Probably difficult to get lower level that protocol checking but wanted to shout.

I was able to review with www.google.com but not https://www.google.com

I could reply even with https...

Yeah we're not trying to detect things that may look like an URL - we used to, when we were transforming them into links automatically, but we don't anymore so really the check is just to add an extra layer to keep our ratings as clean as possible.

when we were doing that detection it was very prone to errors. There are some many TLDs these days that it's too messy.
