Spelling mistake for UnknownGrpcStatusCodeError

[ohmycaptainnemo]

Describe the bug
Hi all. Love the project. This is really not a bug, but rather a spelling mistake I came across and I thought maybe whoever is doing the next pull request should just fix it if that is ok?

To Reproduce
I came across this while trying to catch an UnknownGrpcStatusCodeError which is misspelled as UnkownGrpcStatusCodeError.

pyzeebe/pyzeebe/errors/zeebe_errors.py

Line 18 in 7700d0a

class UnkownGrpcStatusCodeError(PyZeebeError):

Expected behavior
UnkownGrpcStatusCodeError should be changed to UnknownGrpcStatusCodeError here:

pyzeebe/pyzeebe/errors/zeebe_errors.py

Line 18 in 7700d0a

class UnkownGrpcStatusCodeError(PyZeebeError):
