[Bug]: loglevel=error triggers schema validation error in angular/start-storybook

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
