8.x-1.x version of context_redirect

I have created an issue fork so its easier to work on and grab the WIP under a Drupal 9-10 site.

https://git.drupalcode.org/issue/context_redirect-3008452/-/tree/3008452...

I cleaned up Drupal 8 deprecations and minor bugs and formatting. Initial tests of simple redirects appear to work.

Notes:

• This requires Drupal 9.4 at a minimum
• This needs a much updated README (I left it out because it seemed centered on Drupal 6)
• This could benefit from unit or kernel tests

Merged to 2.0.x branch. Work to continue.

Automatically closed - issue fixed for 2 weeks with no activity.
