[gp-cli] Validate .gitpod.yml

[andreafalzetti]

Is your feature request related to a problem? Please describe

Currently, using VSCode, yaml-schema validation helps reducing typos or indentation issues in .gitpod.yml. It would be useful to offer the same functionality from the gp CLI.

Describe the behaviour you'd like

gp validate or gp validate config

Describe alternatives you've considered

It'd be interesting if we could also validate .gitpod.Dockerfile

Additional context

That's something we can do from the docker CLI I think 😄

We could leverage https://github.com/xeipuuv/gojsonschema and load https://github.com/gitpod-io/gitpod/blob/main/components/gitpod-protocol/data/gitpod-schema.json to check against.
