feat: add GitFile Component

[raphaelchristi]

This pull request introduces a new GitFileComponent that allows users to analyze Git repositories and retrieve the content of selected files from specified branches. The component provides the following features:

• Repository URL input for connecting to Git repositories
• Branch selection dropdown that dynamically fetches available branches
• File selection interface to choose specific files from the repository
• File content retrieval functionality with binary file detection
• Error handling for various Git operations

Please take a look at the other Git component to check an example on how to use anyio.Path

Thanks for this, @raphaelchristi !

Suggested change

	@asynccontextmanager
	async def temp_git_repo(self):
	"""Async context manager for temporary git repository cloning."""
	temp_dir = tempfile.mkdtemp()
	try:
	yield temp_dir
	finally:
	await asyncio.get_event_loop().run_in_executor(None, lambda: shutil.rmtree(temp_dir, ignore_errors=True))
	@asynccontextmanager
	async def temp_git_repo(self):
	"""Context manager for handling temporary clone directory."""
	temp_dir = None
	try:
	temp_dir = tempfile.mkdtemp(prefix="langflow_clone_")
	yield temp_dir
	finally:
	if temp_dir:
	await anyio.Path(temp_dir).rmdir()

[ogabrielluiz]

This will not work. Use this instead:

Suggested change

	await asyncio.get_event_loop().run_in_executor(
	None,
	lambda: git.Repo.clone_from(
	self.repository_url, temp_dir, branch=self.branch, depth=1, single_branch=True
	),
	)
	await asyncio.to_thread(
	git.Repo.clone_from,
	self.repository_url,
	temp_dir,
	branch=self.branch,
	depth=1,
	single_branch=True,
	)

[ogabrielluiz]

These should be exceptions.

[ogabrielluiz]

Never use asyncio.get_event_loop() because there may not be a running event loop which will raise an error. Always use asyncio.to_thread.

Experiencing issues when loading a Git repository. I also suggest adding real_time_refresh=True, so that as soon as the Git URL is updated, the branch and the subsequent fields are refreshed automatically instead of having to refresh each field manually.

Issue Faced:

[edwinjosechittilappilly]

Utilise real_time_refresh

Also utilise update_build_config to update the fields data instead of multiple refresh buttons.
