Fixing #1127 by making return types of auto-generated functions dynamic

[Mathis-Z]

This should fix #1127 by changing the type of the return variable to match the actual type of the returned value.

Thanks!

This works in my testing and the fix looks right to me.

I've attached a patch which adds an automated test to validate the fix: it fails without it, and then passes with it. Feel free to integrate this into your PR if you'd like! Otherwise, I'll make a follow-up PR afterward :-)

I added your test case. Should be good to merge now.

Thanks!

However, per Godot's pull request workflow, in order for this to be merged you'll need to squash the changes into a single commit:

Sorry, I did not catch that.
