Removes commentary that restated the code, including:
- module-level banners explaining what the conftest does (covered by
Readme.md and the function bodies)
- docstrings on _scrub_response, _before_record_response, vcr_config,
_vcr_disabled, pytest_recording_configure (function names + bodies
are self-evident)
- inline notes about header filtering, match_on, etc.
- per-test docstrings restating the test name
Keeps the two non-obvious notes that aren't recoverable from the code:
the vcrpy/respx httpx-transport collision rationale on
_RESPX_CONFLICTING_FILES, the vcrpy "return None to skip persisting"
contract on filter_non_2xx_response, and the fixture-ordering
dependency on _vcr_record_retries.
