Unable to select Qt 5.15 SDK when creating Qt Quick Application using Qt Creator 10

Overview:

When creating a new Qt Quick Application using the Qt Creator 10 wizard, I am unable to select a minimum supported Qt SDK version less than 6.2. This makes it impossible to create Qt Quick applications for Qt 5.15.x SDKs. However, pre-existing Qt examples build and deploy without any issues.

Steps to Reproduce:

1. Open Qt Creator 10.
2. Select File > New File or Project.
3. Select Qt Quick Application and click "Choose".
4. enter the name, and directory where you want to store the project, and click "Continue".
5. select Build system "cmake" and click "Continue".
6. Notice that "Qt 5.15" is not available in the "Qt Version" spinner list, which only includes versions 6.2 and higher.
7. Click "Cancel" to exit the "New Project" dialog.

Expected Outcome: I expected to be able to select "Qt 5.15" as the Minimum Required Qt Version when creating a Qt Quick Application.

Actual Outcome: I am unable to select "Qt 5.15" as the Minimum Required Qt Version when creating a Qt Quick Application. The "Qt Version" spinner list only includes versions 6.2 and higher, which do not support Qt 5.15.

Additional Information: I have verified that the Qt 5.15 SDK is installed and configured correctly on my system. I have also tested this issue on multiple machines with the same results. Screenshots are attached for reference.
