🪟 🎉 Add integration for Osano/GDPR

What

Closing https://github.com/airbytehq/airbyte-cloud/issues/2426

This adds the full implementation for GDPR and Osano into the product. It will address the following:

• Loads the Osano script/styles only in Cloud now (as per discussion with Andy)
• Add a "Cookie Preferences" button in the sidebar in Cloud settings that will open the Osano drawer. This button will only be shown if Osano is switched to "active" (i.e. production) and thus show the consent dialogs.
• For users in GDRP affected countries make the newsletter an opt-in instead of opt-out during sign-up

Did not test locally, code LGTM

Also did not test locally, but looks good to me 👍

Just curious: is browser timezone a sufficient way to enforce GDPR? Seems a bit unreliable to me, but I don't have a better suggestion.

I agree, this is not a really foolproof way. Luckily this is really only used to determine the default state of the newsletter flag and such I think it's an "okay enough" approach, without requiring to get a third party geo location service in place (which would be the better approach detecting by IP location). Osano itself for showing the right consent banner actually uses a proper IP based approach, so it's really only for the default state of this one switch we're needing to use this weaker approach.
