@oojacoboo Minimum supported php version for ecodev/graphql-upload is ^8.1. But we have continuous integration for php 8.0

Other test errors I will fix by myself

@oojacoboo
There was a bunch of breaking changes.
Finally, all php >8.0 tests passed. Please review a PR !

[oojacoboo]

Dropped 8.0 tests. I'll review the rest of the PR soon. Thanks for knocking this out!

Does it means we drop support for php 8.0? So we can use all range of php 8.1 features from now

[oojacoboo]

Yes, we'd basically be dropping 8.0 support and only supporting >=8.1 with this PR. However, I am wondering why ecodev/graphql-upload has minimum 8.1 support.

Also, I didn't check. What were the test errors surrounding 8.0?

composer install failed so I did not run tests in php 8.0 enviroment.

While I was working for this and previous PR I felt a huge lack of native PHP intersection types. Many docblocks and assertions can be dropped with php 8.1.

With all range of php 8.1 features debugging codebase would be much simpler and I believe graphqlite will evolve much faster.
In my opinion it's worth to drop support for php 8.0 now in any case.
