feat: enables search page seo noIndex from config (#2652)

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

This PR aims to enable the `noindex` 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.noIndex` and check the value from the meta tag related.
