Also, add an example with incremental builds.

Since Rust compile times are so long, you might want to take advantage of incremental builds. To do this, use the configuration below.
- Include the `run_id` in the key to force `actions/cache` to upload a new snapshot after every build.
- Use `restore-keys:` to load the previous build (when there are multiple partial matches, it selects the most recent).
```yaml
- uses: actions/cache@v3
with:
path: |
~/.cargo/bin/
~/.cargo/registry/index/
~/.cargo/registry/cache/
~/.cargo/git/db/
~/.rustup/
target/
key: ${{ runner.os }}-cargo-${{ hashFiles('**/Cargo.lock', 'rust-toolchain.toml') }}-${{ github.run_id }}
restore-keys: |
