[BEAM-10775] Added a typescript precommit job

[KevinGG]

1. The job runs 2 checks: jest for unit tests; eslint for lint and
   format.
2. The job is triggered on change under
   sdks/python/apache_beam/runners/interactive/extensions. Any
   typescript code outside this directory needs to be explicitly added
   to the trigger pattern and the copyTsSource task.
