feat: loosen method sorting rules

[simPod]

Motivation

We use data providers in phpunit that are manually located bellow the test or bellow the set of tests that use it.

testA
providerA
testB
providerB
testCommonFoo
testCommonBar
providerCommon

Since phpunit v10 requires data providers to be static, the ClassStructure rule would detach them from the actual test resulting in:

providerA
providerB
providerCommon
testA
testB
testCommonFoo
testCommonBar

Also there has been a lot of discussion in past on how to order these methods.

Proposal

I propose to loosen the rule and sort methods only by visibility. Specifically:

1. public
2. protected
3. private

The remaining attributes like abstract, final and static will not be taken into account and left for the user to do whatever he considers the best.

V zasade asi nemam nic proti, ale trochu si myslim ze to pak nebude mit moc rad a vsude to bude jinak, jestli by nebyl lepsi ignore toho rule pro testy treba.. idk.

@p4veI

Ignore jen pro testy nejde. Musely by být separate configy.

Mi úplně jinej order nevadí, ale příp. bych to řešil přes rector or sth.
