Error when using ShaderEffect doesn't tell the user how to fix it

Users with inline shader code will get errors like this when porting to Qt 6:

qUncompress: Z_DATA_ERROR: Input data is corrupted
Attempted to deserialize QShader with unknown version 0.
ShaderEffect: Failed to deserialize QShader from :/opacity-mask.frag
ShaderEffect: shader preparation failed for qrc:/opacity-mask.frag

This doesn't tell them that they need to compile their .frag files to .qsb files. A message that says something like the following would enable the user to fix the problem on their own, and much faster:

ShaderEffect: Failed to deserialize QShader from :/opacity-mask.frag. Shader files must be compiled to .qsb files in Qt 6. See https://doc-snapshots.qt.io/qt6-dev/qtshadertools-build.html for more information.
