Due to https://github.com/open-quantum-safe/liboqs-rust/issues/202 it is not
yet possible to build the static Rosenpass version for `i686`. The CI actions
which fail for this reason have been excluded for now. Further on, some
the workflow names have been shortened for better overview.
Now that fenix + naersk are used, we don't have the problem of hour-long
builds of a `pkgsStatic.rustc` running in qemu-aarch64. Thus, we can now
finally add these without a big penalty in CI runtime. In addition to
that, the i686 target is added as well.
- add prettier for yaml and md files
- add `cargo-audit` job
- add `cargo-clippy` job
- fix missing references in readme.md
This includes a reformat of both `readme.md` files
They cause enormous build times because they recompile a `rustc` on a
Qemu based aarch64 system. Until we find a solution for this, let's ignore
them in CI.
