gql to graphql-core dependency mismatch

[stdkoehler]

Describe the bug

gql 4.0.0 allows graphql-core>=3.2,<3.3, but schema introspection fails with graphql-core 3.2.6 when the backend introspection response contains directive location DIRECTIVE_DEFINITION.

Updating only graphql-core to 3.2.11 fixes the issue.

Relevant stack trace:

KeyError: 'DIRECTIVE_DEFINITION'

During handling of the above exception, another exception occurred:

TypeError: deprecated locations must be specified as a collection of DirectiveLocation enum values.

File ".../gql/client.py", line 1265, in fetch_schema
    self.client._build_schema_from_introspection(execution_result)

File ".../gql/client.py", line 184, in _build_schema_from_introspection
    self.schema = build_client_schema(self.introspection)

File ".../graphql/utilities/build_client_schema.py", line 357, in build_directive
    return GraphQLDirective(...)

File ".../graphql/type/directives.py", line 71, in <genexpr>
    else DirectiveLocation[cast(str, value)]

To Reproduce

from gql import Client

client = Client(
    transport=transport,
    fetch_schema_from_transport=True,
)

with client as session:
    pass

Use a backend whose introspection result contains a directive location named DIRECTIVE_DEFINITION.

Expected behavior

Either gql 4.0.0 should work with all allowed graphql-core>=3.2,<3.3 versions, or the lower bound should be raised to a version that supports this introspection result, for example:

graphql-core>=3.2.11,<3.3

Edit:
I just checked your setup.py which specifies "graphql-core>=3.3.0a3,<3.4". Weirdly, my system doesn't install that, when I upgrade to gql 4.0.0 (it kept graphql-core 3.2.6)
Even with a fresh poetry environment gql = { version = ">=4.0.0,<5.0.0", extras = ["requests"] } leads to graphql-core 3.2.11 not 3.3

System info (please complete the following information):

• OS: Windows
• Python version: 3.13
• gql version: 4.0.0
• graphql-core version: 3.2.6 fails, 3.2.11 works

To use gql with the latest pre-release graphql-core versions 3.3.x, you need to install the gql pre-releases versions (using --pre) See the installation instructions documentation which will install at this point the v4.3.0b3 version.
