Issue description

When opening an existing project, comments beginning with "##" for exported variables in GDScript are not displayed in the Inspector panel, which just says No description available. If you resave the relevant script file, the documentation reappears.

Steps to reproduce

Create a new project. Create a Node root node, and add a script to the node:

extends Node

## Oh, look! An exported variable!
@export var glorp = 0

The variable appears in the Inspector panel, but the property's tooltip initially says No description available. If you save the script file, the documentation appears in the Inspector panel.

Now, Quit to Project List and reload the project. The property's tooltip again says No description available. You must make a change to the script file and resave it for the documentation to reappear.

I think this issue will be fixed by #95821
