Fixed bug by copying missing Kaldi scripts

[VicentCano]

What?

Two scripts where added (egs2/TEMPLATE/asr1/utils/data/modify_speaker_info.sh and egs2/TEMPLATE/asr1/utils/data/internal/modify_speaker_info.py) by copying them from Kaldi's github:
https://github.com/kaldi-asr/kaldi/tree/21ae411fd46282726d893e53c05fef5baea64fef/egs/wsj/s5/utils/data

Why?

The recipe failed when using espnet run.sh because egs2/TEMPLATE/asr1/utils/data/modify_speaker_info.sh was missing. This script is a Kaldi script and, by doing a quick search in the espnet repository appears to be used in the espnet recipes for tedlium3, ami, chime6 and tedlium2.
The other script, egs2/TEMPLATE/asr1/utils/data/internal/modify_speaker_info.py, was added since it was required by the first one.

Thanks a lot!
After the CI check, I'll merge it.

Thank you @sw005320!

The CI check failed at test/espnet2/text/test_whisper_token_id_converter.py.
This error doesn't seem directly related to the scripts I added.
I have noticed the same error occurs in the CI check of #5623...

Previous CI bug seems to be fixed with the latest commit. Thank you! Another unrelated error seems to apper in CI, this time while executing a HTTP request related to vits :(.
