Rewrite as URL adding equals sign to end of url.

Patch #64 updated to apply on Drupal 10.2.4.

I tested the last two patches (#71 #64) with core 10.3.5 and both don't work.

Patch #64 applies on Drupal 10.3.x and fixes the issue.
I updated the IS and I believe that comments from #60 and #61 don't apply anymore with the approach followed in the patch.

For novices: please convert #64 patch to a MR to ease maintainers job.

Fixes should be in MRs

Have not reviewed yet.

Working on it.

Created MR for patch #64. Please review it.

Patch #64 is working for me in a Drupal version 11.0.4.
Thank you!.

Have re-ran tests twice and they still fail.

Tests are now passing, moving to Needs Review.

Hi Sayan, thanks for the effort.
Despite the fact that tests have "Pass" status, there's one warning left, and checking the detail says:

Drupal\Tests\Core\Utility\UnroutedUrlAssemblerTest::testAssembleWithExternalUrl with data set #7
Failed asserting that two strings are equal.
--- Expected
+++ Actual
@@ @@
-'https://example.com/test?foo'
+'https://example.com/test?foo='

which sounds like pretty much what we are testing here, isnt?

@igorgoncalves yes, indeed the two strings of urls are different, that is what we need here. Do I need to make changes to test files, to remove the warnings. I don't have much knowledge of phpunit tests, but can look into it.
