This will also set up build cache and is consistent with the AA CI workflow.

The GHA has been archived. Would you try to use

      - name: Install Rust toolchain (${{ env.RUSTC_VERSION }})
        uses: actions-rust-lang/setup-rust-toolchain@v1
        with:
          toolchain: ${{ env.RUSTC_VERSION }}
          components: rustfmt, clippy

@mkulke thanks for getting the work started! minor nit: the commit title could be adjusted to reflect this ^

I'll try to get a couple of other .ymls updated too...
