fix pylint function override errors

[dpaiton]

The pypechain-rendered IERC4626HyperdriveContract file is producing some pylint errors for override methods. This might be related to a recent pylint update. Here's an example:

/home/runner/work/hyperdrive-sdk/hyperdrive-sdk/crates/hyperdrivepy/python/hyperdrivepy/pypechain_types/IERC4626HyperdriveContract.py:115:9 - error: Method "__call__" overrides class "ContractFunction" in an incompatible manner
    Positional parameter count mismatch; base method has 3, but override has 5
    Parameter "args" is missing in override
    Parameter "**kwargs" has no corresponding parameter (reportIncompatibleMethodOverride)
