fix(dagger): run python black formatter #33

	# Docs: https://github.com/OpenGrabeso/clean-cache
	#
	# As we are using caches more and more, we are getting over the GitHubs 10 GB limit.
	# Unfortunately GitHub does does not have very smart cache eviction policy
	# Docs: https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/caching-dependencies-to-speed-up-workflows#usage-limits-and-eviction-policy

	# Each pre-compiled coreboot toolchain takes up around 500 MB.
	# The most space at the time of writing is taken up by coreboot toolchains. At the time of writing we
	# have 7 coreboot versions, each for x86 and arm64, resulting in 72500=7 GB.
	# Thankfully the coreboot toolchains are not re-built that often, but they do take almost 1 hour to build - hence
	# caching is a good idea.
	# To make sure that the toolchains remain available as long as possible, we should start manually cleaning up the
	# cache - making the eviction logic smarter.
