Incompatibility Issue: pyjwt==2.8.0 with cryptography==43.0.0 causes jwt.exceptions.PyJWKSetError

[CherryNick]

Summary
When using pyjwt==2.8.0 with cryptography==43.0.0, an error occurs:

jwt.exceptions.PyJWKSetError: The JWK Set did not contain any usable keys. Perhaps 'cryptography' is not installed?

Downgrading cryptography to 42.0.7 resolves the issue, indicating an incompatibility between these specific versions.

Expected Result
The JWT token should decode successfully without errors when using pyjwt==2.8.0 and cryptography==43.0.0.

Actual Result
An error is raised when attempting to decode a JWT token:

jwt.exceptions.PyJWKSetError: The JWK Set did not contain any usable keys. Perhaps 'cryptography' is not installed?

Reproduction Steps

• Install pyjwt==2.8.0 and cryptography==43.0.0.
• Attempt to decode a JWT token using a JWK set.
• Observe the error: jwt.exceptions.PyJWKSetError.

Workaround
Downgrading cryptography to version 42.0.7 resolves the issue

cryptography<43.0.1 is pinning a vulnerable version of pyopenssl (effected by https://openssl-library.org/news/secadv/20240903.txt) so PyJWT's dependancies probably need to handle the new version.
