fix(plugin-lighthouse): add chromium to dev deps

[BioPhoton]

This PR adds chromium as NPM dependency to the repository. This should enable a development setup that works after npm ci out of the box. Potential further steps are adding chrome to plugin-lighthosue too.

This PR includes:

• new dev dependency chromium
• remove the chrome path handling for windows CI

Note

Our testing setup snippet uses getChromePath which internally does not check for chromium, so I added a fallback.
See: testing/test-setup/src/lib/chrome-path.setup.ts

How to test it for contributors that did not have Chrome installed?

On your local machine:

1. make sure you have no value set for CHROME_PATH in the env variables (optional)
2. ✅ run e2e tests and have them executed correctly
3. 🗑️ deinstall chrome
4. ❌ run e2e tests and have them failing because chrome not found
5. ⬇️ check out this branch
6. ⏳ run npm ci
7. ✅ run e2e tests and have them executed correctly

In the name of all the people not using Chrome, thank you :)

✅Did a check on fresh windows installation without Chrome.

On main branch it complains about no path to Chrome.exe,
on this branch all integration tests pass and chromium path is autodetected as a local path \node_modules\chromium\lib\chromium\chrome-win\chrome.exe
