Update drush conflict to "<12.4.3"

https://github.com/drush-ops/drush/releases/tag/12.4.3 is released.

I think this is the bug the conversation was about: https://github.com/drush-ops/drush/issues/5797 which is fixed in this PR https://github.com/drush-ops/drush/pull/5809 and is included in the release mentioned above.

The MR here does bump the "conflict": to "drush/drush": "<12.4.3", so that's fine.

I would RTBC, but this issues is still on active (as I just realized) instead of NR.
Just wanted to leave my findings in here.
