Description

Describe the bug

Error: Schema validation failed with the following errors:
  Data path "/loglevel" must match pattern "(silly|verbose|info|warn|silent)".

It looks like it is just missed in the list: https://github.com/storybookjs/storybook/blob/3c53875965718fe29b7da26f3fb805d45c3c1da0/code/frameworks/angular/src/builders/start-storybook/schema.json#L149

Reproduction link

https://stackblitz.com/edit/github-azqpmbzi?file=package.json

Reproduction steps

Go to above link Storybook should have crashed and not started properly Terminal should show error

I'd be happy to push a PR for this

Research direction
The bug is in the schema.json file at code/frameworks/angular/src/builders/start storybook/schema.json, line 149. The 'loglevel' enum is missing 'error'. To fix, add 'error' to the enum list. No linked PR yet, but the reporter offered to submit one. Confirm the exact line and test locally.
