Doctool: Remove version attribute from XML header
We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).

<brief_description>
A plugin that advanced tooltip for its handled resource type.
</brief_description>
<description>
Resource tooltip plugins are used by [FileSystemDock] to generate customized tooltips for specific resources. E.g. tooltip for a [Texture2D] displays a bigger preview and the texture's dimensions.
A plugin must be first registered with [method FileSystemDock.add_resource_tooltip_plugin]. When the user hovers a resource in filesystem dock which is handled by the plugin, [method _make_tooltip_for_path] is called to create the tooltip. It works similarly to [method Control._make_custom_tooltip].

Return [code]true[/code] if the plugin is going to handle the given [Resource] [param type].

<description>
Create and return a tooltip that will be displayed when the user hovers a resource under the given [param path] in filesystem dock.
The [param metadata] dictionary is provided by preview generator (see method EditorResourcePreviewGenerator._generate]).
[param base] is the base default tooltip, which is a [VBoxContainer] with a file name, type and size labels. If another plugin handled the same file type, [param base] will be output from the previous plugin. For best result, make sure the base tooltip is part of the returned [Control].
[b]Note:[/b] It's unadvised to use [method ResourceLoader.load], especially with heavy resources like models or textures, because it will make the editor unresponsive when creating the tooltip. You can use [method request_thumbnail] if you want to display a preview in your tooltip.
[b]Note:[/b] If you decide to discard the [param base], make sure to call [method Node.queue_free], because it's not freed automatically.
[codeblock]
func _make_tooltip_for_path(path, metadata, base):
var t_rect = TextureRect.new()
request_thumbnail(path, t_rect)
base.add_child(t_rect) # The TextureRect will appear at the bottom of the tooltip.
return base
