chore: use depth=1 for cloning

[rantoniuk]

It's not needed to clone full history of the repository just to get and spin up docker compose.

I'm not against the idea, but there's something nice in using vanilla commands. Say a more junior git user may be confused when trying to checkout a tag after making a shallow clone. More senior users know when to shallow-clone - say if they intent to make small contribution and such.

grepping for git clone:

$ git grep "git clone" docs/
docs/docs/contributing/development.mdx:git clone [email protected]:your-username/superset.git
docs/docs/installation/docker-compose.mdx:git clone https://github.com/apache/superset.git
docs/docs/quickstart.mdx:$ git clone https://github.com/apache/superset

quickstart.mdx is probably the place where shallow-cloning would make most sense.
