## What

Changed the sponsor_info gate in contributors.py from a string comparison
(`== "true"`) to a truthy check, and updated the test mock to return a
bool to match what get_bool_env_var actually returns.

## Why

get_bool_env_var returns a Python bool, but the comparison checked for
the string "true". Since `True == "true"` is always False, sponsor
information was never fetched regardless of the SPONSOR_INFO env var
setting.

## Notes

- markdown.py already has `_is_truthy()` that handles both types, so the
  rendering side was not affected — only the data fetch was skipped.
- json_writer.py passes sponsor_info through without comparison, so it's
  also unaffected.
