Add missing handover keyword

[mbhall88]

Part of the reason #116 was failing tests was a missing handover keyword that was added in snakemake v6.2.0. I've added that in and updated the lock file due to some other issues alluded to in #116

I've also pre-emptively bumped the version so that when this is merged onto master we can just tag a release on github directly.

I've squashed all of the commits starting with "test". Basically, the pathspec problem encountered in #116 (comment) was an obscure issue with Mac and the name of the default temporary directory. The default Mac temp dir in github actions starts with /private/var/.... Because var/ exists in out .gitignore file, anything in it is ignored, hence the temporary snakefile we create in

snakefmt/tests/test_snakefmt.py

Lines 56 to 70 in 91603a5

	def test_src_dir_arg_files_modified_inplace(self, cli_runner):
	with tempfile.TemporaryDirectory() as tmpdir:
	content = 'include: "a"'
	abs_tmpdir = Path(tmpdir).resolve()
	snakedir = abs_tmpdir / "workflows"
	snakedir.mkdir()
	snakefile = snakedir / "Snakefile"
	snakefile.write_text(content)
	params = [str(tmpdir)]
	cli_runner.invoke(main, params)
	expected_contents = content + "\n"
	actual_contents = snakefile.read_text()
	assert actual_contents == expected_contents

was actually ignored, and thus we didn't reformat it and the test failed.

I fixed this by explicitly setting the tempdir for that test to /tmp.

Can you remind me why this is being done?

What if /tmp does not exist on the host machine the tests run on? Running this with dir="/not_there" fails with FileNotFoundError on my machine

[mbhall88]

It's basically trying to create a directory structure to test that we are searching for snakefiles and ignoring things that should be ignored etc.

I used /tmp as it seems likely to exist in most places and will be auto cleaned up by the OS usually. I can't use the normal temp dir because as I mentioned above, the Mac CI tests fail.

Happy to change the behaviour to something else though if you have a better idea?

[bricoletc]

Would a good alternative be the cwd? So like ., as that is guaranteed to exist?

[bricoletc]

everything else looks fine to me so approved
