Update Chat Reporting Helper iconset

[Madis0]

Minecraft, in collaboration with GamerSafer, created the Official Minecraft Server List.

In there, servers that have chat reporting and profanity filters, plus some manual review, get the Beacon of Safety badge.

As this is the closest official (and neutral) icon we get to represent chat reporting, it is worth prototyping to see if Chat Reporting Helper should use it as well.

Although, some things to note:

• The icon has a much higher resolution compared to our 20x20 one
• The icon represents, among other things, a manual review, so only 5 Bedrock servers have it right now, no Java servers
• Regardless of whether we'd use the original high-res design or a low-res inspiration, we need a lot more icon states than just the presence of the badge
• While it is the official site, it should still get way more popular, otherwise people have no idea what icon is being referred
• Instead of changing icons, we could just change the color scheme as well
