Instead of having to manually having to specify the PCK version every time a PCK is uploaded to the web player or dashboard, this system will detect it instead.
Godot currently only includes the first two numbers of the version (e.g. 3.2).
This means that it is not possible to detect if a PCK was exported using 3.1.0 or 3.1.1.
The feature would make it so that if there is only one version that has the same first two numbers (e.g. 3.2 at the time of writing) no manual input will be needed.
However, if for example a PCK of version 3.1 is uploaded, there will be a choise between 3.1.0 and 3.1.1 only.
