docs(tutorials): complete the storage step

[nweldev]

close blindnet-io/devrel-management#94

BLOCKED by blindnet-io/product-management#983

[nweldev]

@TheKinrar: this step is now ready for review, but I'll keep it as a draft until we fix blindnet-io/product-management#983.

Just ignore the related warning.

Stumbled upon some typos, thought I would also report them, the result is this review is mostly about typos.

We'll have to make some changes to the tutorial(s) in like a week or two when we start using authentication, app scopes and the identity server, but I'd say this is fine for now!

[nweldev]

Thank you very much @TheKinrar. You are perfectly right. IMHO, the best option would be to split this tutorial into multiple component-specific ones and to replace it for real quick start either with a very simple one using the devkit monorepo once the docker-compose config is done to underline the on-premise approach, or a completely new SaaS approach.

[TheKinrar]

I agree. Full self-hosting means at least four components, so we clearly need a docker-compose for that. Besides, it makes things easier, for us, and for users.
