Move the vendor folder to a different name

I made some work related to this for 3.0.x https://git.drupalcode.org/project/gutenberg/-/commit/33bb7a2dd1f4bda825...
There's still some work to done, so we'll use this issue for reference.

Do you have any thoughts regarding doing the folder move in 2.x

Probably not worth it, just to remove a couple lines in the gitlab ci file?

@Eirik, like you pointed out, I'm just concerned of hooks changing the paths. I've already seen it "in the wild" to override some gutenberg css files.
I guess it'll be a workaround to stay for a long time :D
