fix(bootstrapper): use module logger instead of root logging.info() in _resolve_version_from_git_url

[LalatenduMohanty]

In src/fromager/bootstrapper/_bootstrapper.py:770, logging.info() is called instead of logger.info(). This sends the log message to the root logger, bypassing namespace-based log filtering (e.g. filtering by fromager.bootstrapper).

Pre-existing bug from the original monolithic bootstrapper.py (line 1297), surfaced during review of #1226.

Fix: Change logging.info(...) to logger.info(...).
