fix: correct spelling of 'inferred'

[my1e5]

Small fix to the spelling of 'inferred'.

This was picked up by our CI - the typos spell-checker fixed the spelling in our code, but then the pytest error check failed:

=========================== short test summary info ============================
FAILED tests/test_udp.py::test_invalid_osc_message_values[invalid_values0] - AssertionError: Regex pattern did not match.
 Regex: 'Inferred arg_value type is not supported'
 Input: 'Infered arg_value type is not supported'
