[FIX] google_recaptcha: Add key in session_info

Before this commit, if there was a Google ReCaptcha public key
registered on the database, it was given to the backend along with
the assets in the `session_info` global key.

Since this key is meant to be used on the frontend to generate recaptcha
tokens, it should be available there as well.

Now, it is also given to the frontend version of the `session_info` key.
