Merge bitcoin/bitcoin#32415: scripted-diff: adapt script error constant names in feature_taproot.py

b5f580c scripted-diff: adapt script error constant names in feature_taproot.py (Sebastian Falbesoner)

Pull request description:

  While reviewing #31622 I noticed that the constant name `(SCRIPT_)ERR_SIG_HASHTYPE` is used for two different script verification error codes, namely one for legacy and one for Schnorr signatures:

  https://github.com/bitcoin/bitcoin/blob/eba5f9c4b63fe46261fbb3e71b9a94832d105b23/src/script/script_error.cpp#L56-L57
  https://github.com/bitcoin/bitcoin/blob/eba5f9c4b63fe46261fbb3e71b9a94832d105b23/test/functional/feature_taproot.py#L600

  In order to resolve this confusion, this PR adapts all script error constant names in the functional tests (currently only in feature_taproot.py) to the ones used in our C++ codebase (see [script_error.cpp](https://github.com/bitcoin/bitcoin/blob/master/src/script/script_error.cpp)) with a scripted diff. This also makes checking whether we have test coverage for a certain script error easier.
