WebView CG charter update vote

Hi everyone,

As discussed during TPAC 2022
<https://www.w3.org/2022/09/16-webview-minutes.html#t15>, the group is
planning to shift focus into solution exploration. This will require
updating our charter, which requires a vote.

Please cast your vote in this issue
<https://github.com/WebView-CG/charter/issues/11>, which contains more
information on the proposed changes.

Thanks,
~Rayan
