Added pylock to activationevents (#25025)

This fixes #25016

Added some changes to package.json, so that the extension gets activated
whenever there is a file with the name `pylock.toml` or match the
regular expression `r"^pylock\.([^.]+)\.toml$"`.

I followed [PEP 751](https://peps.python.org/pep-0751/#file-name)'s
naming specification.
