PHP 8 requirement for the latest 3.x version

Adding a temporary patch to able to use PHP 7.4

I'd be fine to remove the comma in 8.x-3.x and add a minimum PHP 8 requirement to 4.x, which no more supports Drupal 9.

Still nobody should use D9 anymore ;)

I'm ok with it.

In this case, I think it’s not necessary to add a minimum PHP 8 requirement for 4.x, because the current requirement "^10.3" implies it.

There is a merge request fixing this in 🐛 Version 8.x-3.6 is not compatible anymore with PHP 7.4 Active .
