Update package manager version and role label reference

The package manager version in the package.json file has been updated to pnpm@9.0.0. Also, in membership-role-selector.tsx, the reference in i18nKey for role labels has been modified to include ".label" for better clarity and maintain the consistent schema in the translation files.
