Add support for PHP 8.0

[wells]

Adds remi-php80 and such.

Hmm... the test is failing on:

Package 'php8.0-json' has no installation candidate

Looks like: oerdnj/deb.sury.org#1439 (comment)

JSON is now always included, so no php8.0-json, it's always there

So we'll need to make sure if php_version == '8.0' (or better yet, if it's major version is 8 or more), the json package is removed by default...

(Big +1 to getting this added though... we need PHP 8 support :D

[geerlingguy]

Haha, well... you pushed that commit while I was typing.

Hey Jeff. Yes sir. Just added a set_fact for Debian builds. Fingers crossed. 🥳

Thanks!

I am still facing the same issue for "php8.1-json" while vagrant up.
My configuration:
"geerlingguy/drupal-vm": "^6.0" in composer.json which installs version "6.0.4".

Inside config.yml:
"vagrant_box: geerlingguy/ubuntu2004"
php_version: '8.1'
