ci: Android NDK has too old libc++

The android CI task fails because the embedded libc++ in the NDK is too old.

Can it be bumped?

The android CI task fails because the embedded libc++ in the NDK is too old.

Can it be bumped?

Qt 6 docs claim that it supports Clang 14.0.6 (NDK r25b).

It is possible to build depends with Clang 14.0.7 (NDK r25c) with API level >= 33.

However, the compiler errors remain the same, unfortunately.

Clang 14.0.6 (NDK r25b).

Sure, but the issue is the libc++, not clang. A older libc++ is included in r25, see https://github.com/android/ndk/issues/1530#issuecomment-1659055600

Right. I mean, ~~even the latest Qt~~ the Qt 5.15 codebase cannot be compiled with NDK > 25.

For reference, I guess this was fixed in qt 6.7 then?
