Please add 1189:8890 to the GitHub description

[devkev]

I have the 3x1 + 1 knob version of these keyboards, which uses a CH552G, and so I didn't find this software at first. Can you please add "1189:8890" somewhere in the GitHub "About/Description" field? This will make it show up when people search GH for "1189:8890", which is the main piece of info that they have after getting one of these devices.

You might also consider removing the "CH57x" reference, and/or making it clearer that it applies to a wider variety of this family of chips, eg. "CH5xx/CH5xxx", since people unfamiliar with them might assume that this software won't work with their device because it has a CH552G, which doesn't match the "CH57x" pattern.
