Provide @strapi/plugin-seo support

Is your feature request related to a problem? Please describe.

Currently there is no "official" way to connect the API output of strapi's official seo plugin.

This is no problem as such, but it requires developers to write their own custom code for an issue that could easily be solved by strapi-nuxt.

Describe the solution you'd like

As the @strapi/plugin-seo plugin is very popular, and as Nuxt already provides an easy way to make use of SEO meta tags via useSeoMeta, I recommend to provide a new composable useStrapiSeo that connects both plugins. This composable could complement useStrapiMedia() for outputting seo.metaImage / seo.openGraph.ogImage url's.

Describe alternatives you've considered

Custom implementations / "Googling"

Additional context

I have published a code snippet on how this feature could look like in the most basic implementation. The gist could become the basis for a PR which I'm willing to work on.

Start with the linked implementation gist and the existing useStrapiMedia() composable to understand the module's conventions. Add the proposed useStrapiSeo composable and verify that it connects Strapi SEO fields, including metaImage and open graph images, with Nuxt's useSeoMeta workflow.
