Feat add badges page hashnode theme

[jomefavourite]

Added Badges page to the Hashnode theme starter-kit Preview here: https://blog.favouritejome.dev/badges

Reason for this PR When the view page button for the Badges page is clicked it leads to a 404 page, because the route hasn't been added. For other themes aside from Hashnode theme, I feel it's okay for the badges route not to exist, but for the Hashnode theme, it should show the page if it is marked as visible.

Limitations

• There's no means to get metadata for the badges page, like og:image so this wasn't done
