Bump aiowebostv to 0.1.2

Proposed change

Bump aiowebostv to 0.1.2

Changlog:

• Bump version to 0.1.2 (@thecode)
• Replace ping task with websockets ping task (@thecode)

Diff: home-assistant-libs/aiowebostv@v0.1.1...v0.1.2

This should resolve #43492, some suggested that #49453 is also related the changes to resolve connection issues:

• Remove the ping task and replace it with websockets internal ping task.
  There are few users (mostly in isolated VLAN) that complained that TCP connections to the device never close.
  When the TCP connection doesn't close the disconnect never happens and client stays in a connected state although it is not connected.
• Update the ping interval from 1 to 5 as 1 seems very low value. I have no data to understand why such high ping interval is needed. Tests with two users and myself showed no problems with setting this to 5.
