v1.0.0 Use correct locale when analysing content

This change makes sure the seo plugin uses the correct locale when analysing content.

Breaking change
You now need to provide the seo view with some options:

import multiLanguageConfig from 'config:@kaliber/sanity-plugin-multi-language'
import { SeoAnalysis, typeHasSeo } from '@kaliber/sanity-plugin-seo'

export function getDefaultDocumentNode({ schemaType }) {
  return S.document().views([
    S.view.form(),
    ...(typeHasSeo(schemaType) ? [S.view.component(SeoAnalysis).options({ multiLanguage: multiLanguageConfig }).title('SEO')] : []),
  ])
}

(refer to @kaliber/sanity-plugin-multi-language@2's config.dist.json if you're wondering what shape the multiLanguageConfig should have)
