A snapshot version is a version that has not yet been released which allows us to deploy the same transient version incrementally, without requiring projects to upgrade the artifact version they're consuming. Those projects can use the same version to get an updated snapshot version.
Fixes#70542.
The 3to4 conversion tool was not handling superclass constructors.
We should translate the godot3 syntax:
```gdscript
func _init(a,b,c).(a,b,c):
pass
func _init(a,b,c):
super(a,b,c)
```
Originally, the _init conversion was intended to remove `void` return types from _init functions, as this was disallowed due to #50589.
As that was resolved by #53366, I removed that part of the conversion logic. If a void return type is present on a constructor, the converter now leaves it.

If calling set_mesh with a PrimitiveMesh that has pending update, the
_mesh_changed function would be called twice. The first time before
set_base had been called, which could lead to an ERROR message about
trying to set an invalid surface override material.
Pretty hacky solution but it's better than an infinite loop.
All this import setup needs to be redone, it's very difficult to properly
bail out from an invalid import without triggering reimport loops.
Also fix underline not visible at default editor scale in LinkButton.
Fixes#73319.
* Avoid "property not found" warnings when adding a file for the first
time.
* When no file is added, disable the Generate POT button instead of
printing a warning.
