fix(cli): identify custom patterns that extend the default pattern

If a custom pattern is used, `backstage.json` will not be updated.
However, if the custom pattern extends the default pattern,
`backstage.json` will be updated, too.

Example:

- `@backstage/*` (default)
- `@{backstage,backstage-community}/*`
- `@{extra1,backstage,extra2}/*`
