add preference for previous media icon

[Dan]

Since v132, when playing a video there is a new super-high contrast audio icon now in the tab, it replaced the previous much more subtle icon:

Searching for "icon" in about:config does not reveal anything like "legacy.tab.audio.playing.icon", neither does there seem to be such a syntax for browser themes (at https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/theme ).

There should be a pref that goes something like "legacy.tab.audio.playing.icon" (and maybe additionally a syntax for that icon in manifest.json)
