Prepend library names in AnnotationReader.getDefault() to be compatible with KiCAD 7.0

Since KiCAD 7.0 library names from plugins installed via the Plugin and Content Manager (PCM)
get prepended with `PCM_`. In order to make tab annotations work with KiCAD 7.0 the library
names in `AnnotationReader.getDefault()` need to be also prepended with that string.
