Support php 8

I am targeting this branch, because I need the current version to support PHP 8.

Changelog

Support PHP 8.

The sonata-project/cache-bundle need to support PHP8 first

[4c0n]

@VincentLanglet Actually it seems that it already does: https://github.com/sonata-project/SonataCacheBundle/blob/d0b13b4dcc85272f2235e7fbd50578dd403222b0/composer.json#L22

However this bundle should support the newer version of that bundle:

SonataPageBundle/composer.json

Line 31 in fed26c0

"sonata-project/cache-bundle": "^2.4.1",

[VincentLanglet]

Oh yes indeed, it required the sonata-project/cache-bundle 3.
Another option is to stop using the cache bundle, since it's deprecated.

#1096
sonata-project/SonataCacheBundle#279

@VincentLanglet Is that not a BC break? I'd rather remove it to be honest, but I guess it should be replaced with some integration of the standard Symfony cache support?

It depends how it's done, but I'm not sure. I know nothing about this bundle.

Another easy option could be to add support for php8 to the cache bundle v2.

@VincentLanglet turns out it wasn't too hard to use version 3: #1304
It's probably better to migrate away from the cache bundle to the default Symfony cache in a new major version.
