Update class reference contribution link.

[Ivorforce]

Should be merged together with godotengine/godot-docs#11188.

There seem to be quite a lot of links 'hardcoded' in the .po files as well; those will need to be updated too. Not sure if that can be done by script.

[Repiteo]

We should avoid hardcoding these values where possible. Some of the suggestions rectifying this rely on the following:

I really, really don't want us to have to use a hardcoded workaround like this. Will need @mhilbrunner to clarify if the original ref can somehow be retained (maybe it's already retained?)

[Ivorforce]

I did attempt to redirect the doc_updating_the_class_reference ref name to an external link, but didn't succeed. I'm not sure if it's possible.

[Repiteo]

I'm still not crazy about the hardcoding, but for a 4.5-stable timeframe this is acceptable

Thanks!
