[qt] Querying qmake for QT_INSTALL_TRANSLATIONS returns an incorrect path

Describe the bug

Querying qmake for QT_INSTALL_TRANSLATIONS returns a path containing the base triplet (e.g. x64-osx) instead of the precise one (e.g. x64-osx-release).

This issue may be be macOS-specific because I didn't encounter it on Windows.

Environment

OS: macOS
Compiler: 14.0.3 (clang-1403.0.22.14.1)

To Reproduce

Steps to reproduce the behavior:

./vcpkg install qtbase:x64-osx-release

Query qmake for QT_INSTALL_TRANSLATIONS, example CMake code:

# Get the path to the qmake executable
get_target_property(QT_QMAKE_EXECUTABLE Qt6::qmake IMPORTED_LOCATION)

# Query qmake for the location of the installed Qt translations
execute_process(
    COMMAND ${QT_QMAKE_EXECUTABLE} -query QT_INSTALL_TRANSLATIONS
    OUTPUT_VARIABLE QUERY_RESULT
)

string(STRIP "${QUERY_RESULT}" QUERY_RESULT)

message(STATUS "${QUERY_RESULT}")

Observe the resulting value (path) containing x64-osx rather than x64-osx-release.

Expected behavior

The variable should point to the correct directory that contains Qt's translations.
