Override mindependency for cryptography

[scbedd]

From @chlowell

In a nutshell, we have azure-identity -> cryptography and azure-identity -> msal -> PyJWT -> cryptography. Min cryptography is 2.1.4 for azure-identity but the latest PyJWT requires 3.3+ and will raise given < 3.2. So, mindependency can't pass. I think msal should drop PyJWT but in the meantime I need to pass mindependency. I could just raise azure-identity's min cryptography, that's ugly but I guess workable for a beta release
