Correct fingerprint algorithm to SHA1

[iinuwa]

Entra uses SHA-1 fingerprints throughout the product (in the Portal, CLI, etc.). If you try to use a SHA256 fingerprint in x5t for the client assertion, an error is thrown. Changing it to SHA-1 works.

Furthermore, the JWT specification states that x5t is explicitly a SHA-1 value, and that x5t#S256 is a SHA-256 value.

I think this is a typo and should be fixed.
