ci: fix Sauce Labs E2E browser tests with Sauce Connect 5 and legacy JWP capabilities

- Pass `--proxy-localhost allow` to Sauce Connect 5 (`saucelabs/sauce-connect-action@v3`) in CI workflow to permit remote Sauce Labs browser VMs to access `http://localhost:2000/`.

- Preserve legacy JWP capability keys (`version`, `platform`) alongside W3C capability keys (`browserVersion`, `platformName`) in `protractor-saucelabs.conf.js` for compatibility with Protractor 7 (`selenium-webdriver@3.6.0`).

(cherry picked from commit 5f1ef6e)
