fix/cookies-policy-allow-js

[ziggy-cyb]

Description

The cookies_policy cookie is currently http only, meaning that gtm can't access it to work out what to do with the cookies. This change removes the http only flag from the cookie.

note: kept previous structure of state since merging the two objects caused the cookie to not be set at all.

Type of change

• Bug fix (non-breaking change which fixes an issue)
