can't disable video background playback when enabled via BgPlaybackStudy

[kjozwiak]

Description

There's a bug with Video Background Playback were you can't disable the feature once it's been enabled by BgPlaybackStudy:Enabled. It's currently set to 100% on both Nightly & BETA and set as 25% on release as per brave/brave-variations#496. We should disable BgPlaybackStudy via Griffin on release until we fix the above bug. Users should be able to disable the feature and shouldn't be forced to use it. Originally reported by @A-t-s-u-s-h-i.

Steps to reproduce

1. install any version of Brave on either Nightly, BETA or Release
2. restart Brave and ensure that BgPlaybackStudy:Enabled via brave://version
3. attempt to disable Video Background Playback via Settings

Quick Note: BgPlaybackStudy:Enabled is only enabled at 25% on the release channel as per brave/brave-variations#496.
