No such option: -f for feast CLI

Expected Behavior

feast -f staging/feature_store.yaml apply

should work

Usage: feast [OPTIONS] COMMAND [ARGS]...
Try 'feast --help' for help.

Error: No such option: -f

I think this is just a docs error. The correct flag is --feature-store-yaml if you need this functionality, eg

feast --feature-store-yaml=staging/feature_store.yaml apply

I agree.

I agree.

I'm happy to open a PR to update these docs.

go for it if you have time. :)
