Change incorrect `[/code]` closing tags to `[/url]` tags. The `url` tags for the links to the Unicode code points information use `[/code]` rather than `[/url]` to close them. This results in the links being rendered incorrectly in the IDE--the entire rest of the documentation for each method gets turned into a giant underlined link. This issue was introduced in https://github.com/godotengine/godot/commit/a2271ba3bdaa5fab0f6518a2445b839d36e283eb.
