Add ha_domain to integrations frontmatter

[frenck]

Proposed change

This adds ha_domain to the frontmatter of most integrations pages.
Has been scripted by matching up manifest.json from the code base with the documentation repository. The domain is pulled from the manifest.json file.

Reasoning:

Right now, we try to get the domain from the URL in Jekyll using Liquid. However, this isn't 100% reliable anymore. This makes it more explicit and removed the need for all the current logic we have (removing that is out of scope for this PR).

Furthermore, we can start using the brands repository as well, since the logos and icons from that repository rely on the domain, for more info, see:
