Make a tag/release for v2.2.0

[ivankravets]

Let PlatformIO to import the 2.2.0 version at https://platformio.org/lib/show/1976/SerialCommands

Yes !!!

I switched from Arduino to Visual Studio Code.
and didn't notice for a long time that I got a different version.

Issue still exists, PlatformIO still doesn't "see" v2.2.0.
With a quick lock both library.properties & library.json seems correct, both have 2.2.0.

PlatformIO crawler should have found it (it crawls every 24 hours or so)

Similar problem on PlatformIO forum

Fixed now!
