Support the new `strawberry.Maybe` type

[cpontvieux-systra]

It’s documented in the Strawberry release 0.266.1

The commit is strawberry-graphql/strawberry#3791

To support it, some test should be added to check for a Maybe type and extract the .value if true.

There are helpers in the strawberry code base:

P.S. When I tried to use it with strawberry django, the first thing that crash was in the process_filter method.

Any updates on the status of this?
Using Maybe seems to 'work' for me, at least it doesn't crash in the way described above.

However, the default value still differs from what I'd expect based on strawberry's regular behaviour:

strawberry.input

The following results in a default value of None

@strawberry.input:
class MyInput:
  my_field: Maybe[bool]

strawberry_django.input

The following results in a default value of strawberry.UNSET

@strawberry_django.input(MyModel):
class MyInput:
  my_field: Maybe[bool]
