feat: enables search seo noFollow from config (#2656)

## What's the purpose of this pull request?

This PR aims to enable the `nofollow` prop from NextSeo from the
discovery.config value.

## How it works?

The default value is true as was previously, but the stores can switch
to false as needed.

## How to test it?

You can switch the value from `discovery.config.js `->
`seo.search.noFollow` and check the value from the meta tag related.
