Fix M5stickC Plus2 backlight blinking when inactivity timeout

[hijae]

First of all, thank you for your project. I'm using it very well.
But backlight doesn't turn off on the m5stickc plus2.
so set Brightness to 0.

I've tested it and it works fine on me. But you need to check how it works on other devices.

@hijae Thank you for the PR.
Hmm, I do not see this behaviour with my M5StickC Plus2.
Can you share a few more details on your setup (eg. firmware version) so I can try to reproduce?

I would like to avoid disabling the backlight completely, otherwise it is difficult to tell if the device is off or sleeping.

Ah, I found it.
The web installer is using an old beta version for some reason.
This was fixed in #86.
Hmm, I need to find out why the web installer is not up to date with v2.0.0.

OK, I messed up recently when playing with the web installer deployments.
I have rolled it back to the correct v2.0.0+1 deployment (it was previously on v2.0.0-beta+1).

@hijae Thank you for finding and raising this, I appreciate your time and effort.
Closing as "Oh dear, I messed up".
