raise deployment target from ios11 to ios12

this is needed as otherwise there are weird crashes,
eg. when opening connectivity view
(there are sth. simple as `let monitor = NWPathMonitor()`)

as reported eg. at
https://github.com/fluttercommunity/plus_plugins/pull/2169
it seems xcode15 does not support ios<12 fully

fortunately,
this does not change our minimum supported devices as
all of them get get ios12.
