Throughout QtCreator version numbers appear in lexicographical order rather than "natural"  or "human" order.

This is confusing.

Is Qt 5.15 newer than 5.2? No.
Then why does Qt 5.2 show up BELOW 5.15?

Places where this applies (from a quick check, there may be others)

• Autocomplete for imports
• "Projects" tab where different build environments are maintained
• Initial target selection when a CMakeLists.txt.user is not found

Current behavior is to display in lexicographical ascending order.

Ideally versions should show in "natural" descending order.

```

import QtQuick ___

                         6.5

                         6.2

                         2.15

                         2.13

                         2.9

```
