Enable BraveBlockScreenFingerprinting for Beta Desktop users

[arthuredelstein]

Now that Screen Fingerprinting is at 100% of users on Desktop Nightly, we can roll it out to Beta users. We did previously have this protection at 100% for Beta users, but then temporarily rolled it back while we uplifted a fix for brave/brave-browser#27021. So my suggestion is to deploy for 100% of Beta users now, and then if everything looks good we can roll it out gradually in Release.

@arthuredelstein has this been rolled out to release?

Hi @bsclifton, it's currently only rolled out in Nightly. This issue is to roll it out in Beta, and if that looks good then we would roll out in Release.
