fix(plugin-seo)!: data types plugin seo (#6979)

Changed the data to correctly match type generic being sent to the
generate functions. So now you can type your generateTitle etc.
functions like this

```ts
// before
const generateTitle: GenerateTitle = async <Page>({ doc, locale }) => {
  return `Website.com — ${doc?.title?.value}`
}


// curent
import type { GenerateDescription, GenerateTitle, GenerateURL } from '@payloadcms/plugin-seo/types'
import type { Page } from './payload-types'

const generateTitle: GenerateTitle<Page> = async ({ doc, locale }) => {
  return `Website.com — ${doc?.title}`
}

const generateDescription: GenerateDescription<Page> = async ({ doc, locale }) => {
  return doc?.excerpt || 'generated description'
}

const generateURL: GenerateURL<Page> = async ({ doc, locale }) => {
  return `https://yoursite.com/${locale ? locale + '/' : ''}${doc?.slug || ''}`
}
```

Breaking change because it was previously a FormState value.
