feat!: add a default global ID encoder, add a id_field on the query type

[pkucmus]

BREAKING CHANGE: the global ID function takes only a str with the GID, the query type uses the id_field arg to determine which kwarg to pass to the decoder

One would be able to do:

query = RelayQueryType(
    id_field="bid",
)

Instead of this:

def decode_global_id(kwargs) -> GlobalIDTuple:
    return GlobalIDTuple(*b64decode(kwargs["bid"]).decode().split(":"))


query = RelayQueryType(
    global_id_decoder=decode_global_id,
)

With the following:

ariadne/ariadne/contrib/relay/objects.py

Line 122 in 2c8f064

type_name, _ = self.global_id_decoder(kwargs[self.id_field])

This is to make the decoder a bit dummer as to take the responsibility of pulling the GID from the right kwarg (or query param, if you will) from the decoder and leave it with the single responsibility.
