Fix GHA Firefox & Edge browsers

[jh27539]

Purpose

The Problem
Browsers normally have a user agent field that looks like this:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/139.0.0.0 Safari/537.36

Originally, I was trying to append a "Selenium Bot" tag to the existing user agent field in order to preserve this information.

1. Launch browser
2. Collect default user agent
3. Close browser
4. Re-launch browser
5. Append user agent field

This worked great locally, but re-launching browsers is not compatible with github actions workflows.

The Fix
Scrap the extra steps and just override the user agent tag to say OSF Selenium Bot. This is good enough for our devops folks to monitor our daily automated traffic.

Summary of Changes

• Stop relaunching browsers to collect user agent fields & override them
• Instead, just launch browser once with OSF Selenium Bot custom tag
• Bonus: Upgrade OS version to Windows11
