feat: support apollo federation spec v2.7 and higher

[jjangga0214]

When targeting v2.6, hive dev works.

extend schema

But it doesn't for v2.7 and higher(e.g. ~v2.10).

It's not supported yet, as @override(label:) is an enterprise feature in Apollo.
Can you explain why do you need that version? You specifically want that label argument or you're only testing if version 2.7 is supported?

[jjangga0214]

Ah, I see.

you're only testing if version 2.7 is supported?

Yes, I was only testing whether higher versions are supported.
