[Dep] Update to php 8.1 requirement (manual)

[samsonasik]

@TomasVotruba this is split of #1364 with manual change only with teskipped:

• rectify CI
• commented MyCLabsClassToEnumRector and SpatieEnumClassToEnumRector as it make Enum syntax upgrade needs to be skipped as it change PhpVersion class that extends :

use MyCLabs\Enum\Enum;

- final class PhpVersion extends Enum
+ enum PhpVersion : int

which will need update currently manually of its usage:

-PhpVersion::PHP_52;
+PhpVersion::PHP_52->value;

and it seems cause change

also other Enums, eg ObjectReference and ApplicationPhase manually:

-        if ($node->toString() === ObjectReference::PARENT()->getValue()) {
+        if ($node->toString() === ObjectReference::PARENT()->value) {

-        }, ApplicationPhase::PARSING());
+        }, ApplicationPhase::PARSING->value);

and we may need to create a downgrade rule for it to keep working on scoping.

I commented the rules at 99fa67b

@TomasVotruba all green 🎉 it is ready for review.

Note: the pending CI PHP 8.0 are probably cache or need you to disable it?

It's because of requried names of jobs that must pass. Unfortunatelly Github sees thems as string, it's based on workflow name.
So changing string from "8.0" to "8.1" required manual change in settings. I'll handle it.

-PhpVersion::PHP_52;
+PhpVersion::PHP_52->value;

Instead, the code using these enums should be upgraded from string to the Enum, e.g.:

interface MinPhpVersionInterface
{
-    public function provideMinPhpVersion(): int;
+    public function provideMinPhpVersion(): PhpVersion;
}

It should be handled in separated PR, maybe via a new Rector rule.

[TomasVotruba]

These should be included in set so others can use them, but be skipped in our rector.php.
