Fix: geometry nodes modifier property not working after changing it in Python

This affected only vector and color inputs. The issue was that those were
expected to be stored as float-array properties. However, when setting them
from python using `modifier["Input_X"] = [1, 2, 3]` the array type becomes
either `int` or `double`, but not `float`. A workaround was to use
`modifier["Input_X"][:] = [1, 2, 3]` as this changes the property inplace.

Now `int` and `double` arrays are also understood by the modifier.
