py files doesn't have to be checked is_zipfiles in process_files

[sungpeo]

py files doesn't have to be checked with is_zipfiles in process_files
like find_dag_file_paths in file.

airflow/airflow/utils/file.py

Lines 192 to 201 in 0a2d0d1

	def find_dag_file_paths(directory: Union[str, "pathlib.Path"], safe_mode: bool) -> List[str]:
	"""Finds file paths of all DAG files."""
	file_paths = []
	for file_path in find_path_from_directory(str(directory), ".airflowignore"):
	try:
	if not os.path.isfile(file_path):
	continue
	_, file_ext = os.path.splitext(os.path.split(file_path)[-1])
	if file_ext != '.py' and not zipfile.is_zipfile(file_path):

zipfile.is_zipfile could take longer than anticipated in case of remote file mount (DAG_DIR).
So, I want py files (generaly almost dag files are py) skip to check is_zipfile.

(It is simple change. Exist tests cover this one)

I am ok with this change. Looks reasonable. It has (very improbable) compatibility if someone would have stored a zip file as .py file. This is unlikely, and I think it does not "count" as backwards compatiblity, but this behaviour change should be mentioned in UPDATING.md

Also I think we need someone else from committers to also agree that this not "incompatible envough" to classify as backwards-incompatible.

The PR most likely needs to run full matrix of tests because it modifies parts of the core of Airflow. However, committers might decide to merge it quickly and take the risk. If they don't merge it quickly - please rebase it to the latest main at your convenience, or amend the last commit of the PR, and push it with --force-with-lease.
