feature: add support for installing only specified browser dependencies

It would be useful if we could do something like:

      - uses: microsoft/playwright-github-action@v1
        with:
          browsers: chromium, webkit

or

      - uses: microsoft/playwright-github-action@v1
        with:
          browsers: chromium

Since the apt calls are already separate only a call to getInput and some parsing would be required.

(I’m open to collaborate for that feature)

Thanks @mxschmitt! Can you elaborate more on when this would be useful?

A use case would be e.g. when you need only webkit and Chrome but not firefox. You can save the time and bandwidth to only install their dependencies in the end. Could save on some environments around 20 seconds.

Its now possible via the CLI: https://playwright.dev/docs/cli#install-system-dependencies

for example: npx playwright install-deps chromium
