Rustler precompiled segfaults in GH action

I changed the workflow to use:

- name: Install Rust
  uses: dtolnay/rust-toolchain@stable
  with:
    toolchain: 1.86.0  # Specify your desired Rust version
    targets: ${{ matrix.job.target }}

instead of

- name: Add target
  shell: bash
  run: |
    rustup target add ${{ matrix.job.target }}

Now it uses rust 1.86 and that works!

Thanks for the assist!
