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 wrapper class for web native JavaScript objects.
</brief_description>
<description>
JavaScriptObject is used to interact with JavaScript objects retrieved or created via [method JavaScriptBridge.get_interface], [method JavaScriptBridge.create_object], or [method JavaScriptBridge.create_callback].
[b]Example:[/b]
[codeblock]
extends Node
var _my_js_callback = JavaScriptBridge.create_callback(myCallback) # This reference must be kept
var console = JavaScriptBridge.get_interface("console")
func _init():
var buf = JavaScriptBridge.create_object("ArrayBuffer", 10) # new ArrayBuffer(10)
print(buf) # prints [JavaScriptObject:OBJECT_ID]
var uint8arr = JavaScriptBridge.create_object("Uint8Array", buf) # new Uint8Array(buf)
uint8arr[1] = 255
prints(uint8arr[1], uint8arr.byteLength) # prints 255 10
console.log(uint8arr) # prints in browser console "Uint8Array(10) [ 0, 255, 0, 0, 0, 0, 0, 0, 0, 0 ]"
# Equivalent of JavaScriptBridge: Array.from(uint8arr).forEach(myCallback)
JavaScriptBridge.get_interface("Array").from(uint8arr).forEach(_my_js_callback)
func myCallback(args):
# Will be called with the parameters passed to the "forEach" callback
# [0, 0, [JavaScriptObject:1173]]
# [255, 1, [JavaScriptObject:1173]]
# ...
# [0, 9, [JavaScriptObject:1180]]
print(args)
