Fix e2e & test CI workflows

[ankur22]

This issue is related to the issue with chromium crashing in the test ci workflow. We opened an issue with github and they opened an issue with the chrome team.

In addition to the above, github runner images have both chromium and chrome installed. The browser module defaults to working with chromium over chrome on linux machines. The version of chromium on the github runner images doesn't have the fix to prevent it from crashing, but the version of chrome is up to date.

There are several things to resolve with the workflows:

1. The test workflow should work with ubuntu-latest.
2. The exec path for chrome should be set to /usr/bin/google-chrome on linux runners.
3. The e2e workflow should work with ubuntu-latest.
4. Use the matrix in the e2e tests. It's defined but then never used.
5. Remove the install/setup step for linux runners in the test workflow.
6. Fix any tests that are failing consistently:
   1. The TestBrowserRegistry are very flakey.
   2. The hosts.js example is failing on Windows.

A PR with most to these changes has already been created. What remains are the fixes for the failing (flakey) tests.
