Switch from ip to tz for takeovers.

[carkod]

Done

• As a follow-up of Sam's work, move to the timezone system for takeovers instead of IP addresses.
• Remove IP address geolocation

QA

• Go to https://discourse.ubuntu.com/t/takeover-french-business-guide-to-multicloud/34968
• Edit the post and set target_country to your country code
• Go to the demo homepage, reload a bunch of time until you see that takeover.
• Please if you not in too much of a hurry, revert back the Discourse takeover change.

Instead of removing the alternative method of finding a user's IP, could we keep it as a fallback?

Why do we need a fallback? What's your concern?

[samhotep]

@carkod do we know where else it was being used? IIRC we kept it because takeovers needed it, but if that was all we can remove it

@carkod also the page here https://discourse.ubuntu.com/t/takeover-french-business-guide-to-multicloud/34968 doesn't seem to exist

@carlos as we discussed it might be better to convert the timezone to lowercase https://github.com/canonical/ubuntu.com/blob/5d4771a8d9d58f9ed0069e88807e870ea785aac4/templates/base_index.html#L1142C28-L1142C42

Since takeovers use lowercase for target_country
