Store and write the project version about gdscript-docs-maker

[Razoric480]

It's actually stored in the export_presets.cfg, and is set per-preset. Under GDScript it'd be something like:

var file := File.new()
if file_exists("res://export_presets.cfg"):
	var export_config := ConfigFile.new()
	var config_error := export_config.load("res://export_presets.cfg")
	if config_error == OK:
		var product_version = export_config.get_value(
				"preset.0.options",
				"application/product_version"
		)
		if product_version:
			print(product_version)

For things that aren't going to be exported, it's not exactly convenient. May need to add our own string in the ProjectSettings as custom data, or edit the reference.json file once it's been generated.

There's also this plugin that I stumbled on, though it's for 2.1 and it hasn't been updated in 2 years.

This pull request should solve this issue once it's merged 🙂

Thanks, I'll look at the version format and implement something sometime

How about writing this? Where should I put the version number? The tool generates standalone markdown files for each class. Should we write the version number in each of them? Or should we write an index.md file with e.g. a TOC and the main project information?

[Razoric480]

The project.godot DOES have a Project Name and Project Description. Seems like pretty apt to put that in a main index.

And if we add categories, we can make the TOC work pretty well. Which brings us back to #29

Alright I'll mark this as solved and move the requirements to #29
