fix: ignore_paths are now checked before we do any translation logic

Purpose/goal of Pull Request (Issue #)

https://wovnio.atlassian.net/browse/ST-2310

The original problem is on our dashboard, the user gets redirected back to English even if they have selected Japanese. This is fixed by adding the use_cookie_lang feature. However, this created a new issue where it messes up widget XHR session auth. Those requests should not be redirected.

I noticed a few related issues in this area

Comments

1. ignore_paths should be checked before we do anything else. This is what every other backend does
   • use_cookie_lang
   • explicit default lang redirects
2. Remove language condition on ignore_paths. ignore_paths should be literal and really means do nothing if the request
   matches it. This is consistent with other backends as well.
   • /ignored_path?wovn=en should be ignored.
   • I made it a major version bump due to the change in behavior
   • This came from Fully ignore paths that exist with (not added by WOVN) language code #146 originally. Looking back on it, I don't think it was correct. We should follow our spec from other backends.
3. To actually fix the problem, rather than require setting ignore_paths for every known widget/live editor request (error prone when we add more) I added a check for requests for X-Wovn-Widget header. We will ignore these requests automatically. Can't do this because it violates CORS limits

In the end, I think this is not the best way to fix the original problem since we have to be very careful with /ignore_paths. The dashboard should instead be generating links in the correct language.

So, this change is still good for the bug fixes to ignore_paths but we will not turn on use_cookie_lang to solve the dashboard issue which is safer for the widget.
