Handling relative paths does not consider the default working-directory

I notice that I get an error when reading the file in the following job snippet:

```
rust-bench:
name: Rust bench
timeout-minutes: 20
defaults:
run:
working-directory: ./src/example
steps:
- name: Checkout
uses: actions/checkout@v4
with:
persist-credentials: false
lfs: true

- name: Install Rust
uses: dtolnay/rust-toolchain@stable
- name: Run bench
run: cargo bench --bench my-code | tee results.txt

- name: Store bench with github action
uses: benchmark-action/github-action-benchmark@v1
with:
name: Rust Benchmark
tool: 'cargo'
output-file-path: results.txt
github-token: ${{ github.token }}
auto-push: true
summary-always: true
alert-threshold: '110%'
comment-on-alert: true
fail-on-alert: true
```

From the error, I can see it's ignoring the working-directory parameter.
After I added the `src/example` to the `output-file-path` the action success to read the file
