Deprecate node_get_type_label()

Missing the @trigger_error()?

woops!

The change looks good.

I'm unsure about the D12 deprecation, while it's trivial and not used a lot, the suggested replacement requires 11.3. I'd suggest we expand the change record, mention that getBundleEntity is 11.3+ and suggest using $node->get('type')->entity->label() as an alternative which is fully backwards compatible and then we'll see if core maintainers are OK with that.

But the deprecation is also in 11.3, but I see where you're coming from for modules supporting both 11.3 and 11.2.

I've updated the CR.

CR reads fine and a good deprecation. Not sure what else to review..
