Brave-browser: Create a new icon for Muon Brave to show its deprecated

[bsclifton]

During the Muon => Brave Core review today, we discussed having a new application icon for the Muon version of Brave. This would help make it more obvious that the application is deprecated. It should also help differentiate the old browser in situations where the user is changing default browser (helping them correctly pick the new Brave Core version, which has the expected icon)

@bradleyrichter updating these should be fairly easy- we'd only need to update the Release channel icon. Here's a list of the resources I am aware of:

• [x] https://github.com/brave/browser-laptop/tree/master/res/dev/app.png
• [x] https://github.com/brave/browser-laptop/tree/master/res/dev/app.ico
• [x] https://github.com/brave/browser-laptop/tree/master/res/dev/app.icns

We don't need to bother updating the installer icons since the installer won't really be available anywhere

Proposed icon (during the presentation today) was to use the regular icon with the banner text Old (instead of Beta or Dev). We could also try different colors (whatever makes sense)

Looped in with @bradleyrichter for a proposed icon update for this. Changing it to a lighter grey version with the outdated version number attached to it. If all looks good I can work up those icon assets outlined above for it.

@rossmoody love it! 😄 What do you think @rebron @davidtemkin @bbondy @kjozwiak?

[davidtemkin]

I think we need to say "Old" in place of the "0.25" for clarity. Users are unlikely to be aware of our version numbers or the meaning thereof.

[kjozwiak]

I personally like the above design but I agree with @davidtemkin. There's a good amount of users out there that don't understand versioning and might have issues associating a particular version number to muon. I've ran into several situations where a user that needed support had both browsers installed, but had a hard time distinguishing which one is the newest via the version. Most users usually associate the browsers via the differences in UI. So adding a version number might not work for most users who just don't keep up with version numbers.

A similar thing would happen if we used the same icon for all three channels but added version numbers. Some users might figure out that the higher the version number on the icon, the newer the build. But a good percentage of users will see it as a random number that means nothing to them.

I'm not sure if this is a valid concern, but we use the above icon for master builds in b-c. Probably doesn't matter though, just wanted to point it out just in case.

[bradleyrichter]

My concern is that "old" doesn't translate well and may become a twitter meme. Quickly looking at a couple of other options...

Alright @bsclifton updated icon files here from fresh approved direction of @davidtemkin @bradleyrichter

Gonna go with a faded grey lion.
