RapidPE-RIFT for online PE

This MR adds rapidpe-rift workflow to online PE.

• gwcelery/tasks/inference.py: add tasks for rapidpe-rift
• gwcelery/tasks/orchestrator.py: trigger rapidpe-rift runs as well for triggers which require PE followups. They are only triggered for gstlal triggers for now, as rapidpe-rift-pipe is compatible only with them.
• gwcelery/templates/rapidpe.jinja2: add ini template for rapidpe-rift
• gwcelery/tests/test_tasks_inference.py: add unit tests for rapidpe-rift workflow
• pyproject.toml: add packages required for rapidpe-rift runs

TODO

• Release updated versions of rapidpe, rift, and rapidpe-rift-pipe
• Add them to pyproject.toml and poetry.lock
