fix(archivebox): Remove unused `postgres` section from `questions.yaml`, add docs (#18488)

**Description**

The `postgres` section in `questions.yaml` was added by accident in the
[original new chart PR](https://github.com/truecharts/charts/pull/18258)
because I copy-pasted a template from an existing project to modify and
didn't notice that line.

Additional minor changes included:

- enable pod `liveness` `probe` on `/health/` by default
- explicitly set `runAsNonRoot: false` and ingress port `protocol: http`
- add new `docs/installation_guide.md`

**⚙️ Type of change**

- [ ] ⚙️ Feature/App addition
- [x] 📖 Documentation addition
- [x] 🪛 Bugfix
- [ ] ⚠️ Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] 🔃 Refactor of current code

**🧪 How Has This Been Tested?**

Tested in TrueNAS scale by installing incubator chart `archivebox` and
setting postgres instaces to 0.

**📝 Notes:**

I still need help with a `missing Chart.yaml` error to get this working:
