Sync requirements.txt with pyproject.toml runtime deps (#1085)

requirements.txt was missing pydantic, pyyaml, and numpy, which are all
declared runtime dependencies in pyproject.toml. pip install uses
pyproject.toml so most users were unaffected, but anyone installing via
'pip install -r requirements.txt' (dev/CI setups) would hit
'ModuleNotFoundError: No module named pydantic' at runtime.

pydantic underpins the JSON output schema (scalene_json.py) and the
LineNumber type in scalene_statistics.py, so it is a hard dependency.
