dd625fbf - Remove `lerna bootstrap` from the `clean` script in package.json (#88527)

Remove `lerna bootstrap` from the `clean` script in package.json (#88527) In #87188 we upgraded lerna to v9 which no longer supports/requires the `lerna bootstrap` command. This commit removes it from the `clean` script in the root package.json to avoid errors when running `pnpm clean`.
