Remove unused tools to free up CI disk space

[jul-sh]

Currently it seems our CI workflow is running out of space.
Some PRs where this is happening:

#1843
#1846
#1857

This tries to patch it by removing some prebuilt tools included by GitHub to free up more space.
An approach recommend here: actions/runner-images#709 (comment)
And used by big repos such as https://github.com/facebook/proxygen

Seems quite effective, cleans up an additional 7GB compared to our previous setup.
In fact, I'm tempted to remove the current line disabling the swap file. It's only 512MB and disabling it seems a bit unsafe: https://help.ubuntu.com/community/SwapFaq#Why_do_I_need_swap.3

Thank you @juliettepretot ! I was dreading the process of figuring out why CI was broken for #1846 and now I don't have to!
