[electrum] regenerate protobuf files

Summary:
Update the protobuf files in the newer format supported by protobuf versions > 4. This makes it possible for users with a newer version of protobuf installed to use Electrum ABC.

For now we keep protobuf 3.20 as the official requirement, because this is the only version supporting both the old and new protobuf format. Our dependency to keepkey makes it hard to drop support for the old format (see description of the issue here: https://github.com/spesmilo/electrum/issues/7922)

There is ongoing work for trying to make keepkey work with the new protobuf format, but for now I have not been able to use it succesfully. See https://github.com/keepkey/python-keepkey/issues/146

Note that I generated the files with protobuf 5.28 and then manually removed the runtime version check which is not supported by protobuf 3.20

I compared the generated paymentrequest file with the one electrum uses and did not find any other discrepancy that could cause an issue with protobuf 3.20

Test Plan:
python test_runner.py

Wait for a successfull fusion.
