make format_all.jl path independent

Before the format_all.jl script needs to be execute from the project root directory. Now the script can be executed from every directory path.

Thanks for this. No concerns from my side.

There is just one minor issue, which is not directly related to this PR: the .formatting/Manifest.yml is outdated and uses Julia==1.8.1, which is not compatible with Julia=1.9 used in the CI. If you want, you can fix this in the current PR, if not, I will open a respective issue.

We should discuss it in general, if we should add the Manifest.yml to the repository. I know it make it reproducible but is this required for a library? I found this answer: https://discourse.julialang.org/t/does-manifest-toml-belong-in-the-repository/12029

In my opinion, we should remove it because the reproducibility is not important if we provide the QED packages for other projects/applications. The advantages would be, that we avoid unnecessary warnings with the different Julia versions and it reduce the noise in PRs.

As discussed offline, the manifest files will be removed in a separate PR.
