Remove pathauto version check from 9.0, no incompatible version is Drupal 9 compatible

The check is in system_requirements()

Now you basically make it always fail. You should remove the whole block.

I doubt we have tests for this, so if this passes then it's IMHO good to go. This currently makes D9 testing harder as it doesn't handle dev version, which you currently need of pathauto and it's duplicated by the core-compatibility check now as these old versions are not D9 compatible anyway. This D9 only.

Actually, that's not all, there's also a conflict definition in composer.json that we can remove.

this means we need to update the composer lock hash, try composer update --lock with the patch applied.

Was a random fail. Looks good now. patch is for 9.1.x now, I think this can also be done on 9.0, but apparently will require a reroll for that?

> it's not really doing any harm

It kinda does, because you get errors about pathauto being incompatible if you test D9 with pathauto 8.x-1.x-dev right now, which is the only compatible version. But I'll do a new release soon, that will solve that problem as well.
