chore(playwrighttesting): use playwright OSS types (#32319)

### Packages impacted by this PR

@azure/microsoft-playwright-testing

### Issues associated with this PR

Type changes by playwright OSS will impact
@azure/microsoft-playwright-testing SDK if relevant types are hardcoded.

Also fixes #32394

### Describe the problem that is addressed by this PR

Instead of having playwright OSS types hardcoded in the package, we will
use the types provided by the playwright OSS package itself (Playwright
OSS is added as a peer dependency).

This also changes peer dependency version of playwright OSS to v1.47,
which is the minimum supported version of playwright OSS for this SDK.

chosen?
