Double segmentation fault, ouch.

Suggested change

	'pytest-codspeed; python_version == "3.14" and implementation_name == "cpython"',
	'pytest-codspeed; python_version == "3.13" and implementation_name == "cpython"',

(or update the benchmarks job)

Double segmentation fault, ouch.

We need to wait for uv to ship the beta1, things work with 3.14.0b1 built locally.

[davidhewitt]

Ah yes, the ABI changed between alpha 6 which this CI ran with and beta 1, so it's no surprise stuff is broken.

[xtexx]

generate_self_schema.py also needs to be updated. Could you please merge xtexx@fc48a23 into this PR?

It is going to be removed in #1715.
