Add an option to auto-fix the return type of a Microflow

Currently, whenever you return the wrong type of variable in a Microflow, an error will appear stating “The microflow expression is of type X but should be of type Y”. It would be nice to have an option to double click / right click this error with an option to automatically change the return type to the detected type X.

This same idea could work when creating variables, just add an option to change the variable type.
