Add an option to log output to file

**Context**

I'm using Cypress Cloud and what I want is that for each test run, a link to the Cypress Cloud run should be included somewhere in the PR.

We could do this by setting up a Github Action that comments the link in the PR - but how to get the link?

We can grep it from std out - the bit that says: Recorded Run: https://cloud.cypress.io/projects/xyz/runs/16, but how to get access to this?

I could log it to file:
```
- name: Execute Cypress
uses: cypress-io/github-action@v6
with:
command: npx cypress run | tee cypress-output.log
wait-on: http://localhost:8080
record: true
```

The problem with this is that it that the additional commands (--record) will be tacked on to `tee` not `npx`.

What would be nice if you can add an option like:

```
output_log: 'cypress-output.log'
```

That will also record std out as a file.
