Google Analytics - Incomplete implementation

[Coedice]

There is a Google Analytics JS script, but the _config.yml only has a placeholder for the Google Analytics ID.

Proposed solutions:

1. Add the Google Analytics ID
2. Remove the Google Analytics embed (since if it has been not working so far, it probably isn't being used)

@Coedice, It's been ages since I looked at this but I think the GA ID might be an example/pseudo-ID re-hashed from either Jekyll or GH-P docs. I haven't looked into this since Google ported everything over to GA4. The property is still the old one.

The business analytics don't work either for the Google biz profile but it used to. I keep getting emails claiming that 0 people visit per month, yet when I go online, there's usually between 40-80 business views per month or so, but it's been a while since I checked this substantially.

My latest commits have partially fixed this. However, I'm not actually sure which of the newly ported properties I have connected to the
site. I tried to rename one of them and instead, it appears that it has been duplicated. I do not want to delete the other properties in case I delete the wrong one.
