fix: stop creating root.log on autoarray import

Remove the FileHandler with filename root.log from autoarray's packaged
logging.yaml (and the test config mirror). It attached to the root logger
unconditionally, dropping a root.log into cwd whenever a script imported
autoarray from a directory whose own config/logging.yaml did not override
this one (e.g. running from a repo root rather than a workspace dir).

Console logging via StreamHandler is unchanged.
