Pull request overview
This PR reformats the DNS server troubleshooting page under the unsupported-installation docs to use the repository’s flowing-text style. It keeps the page’s purpose and technical guidance the same, while aligning the prose with the broader Home Assistant documentation format.
Changes:
- Reflows the introductory and solution paragraphs into flowing text.
- Keeps the existing CLI commands and troubleshooting steps intact.
- Applies the same formatting approach to the IPv6/DNS behavior explanation.

@Copilot Did this issue arise as a result of this PR? If not, I will most likely open another PR for this change.

| this situation, particularly around updates and installing software. | ||
| A DNS server handling A and AAAA requests correctly will respond with status `NOERROR` for both of those queries even though there are no answers for the AAAA request. A DNS server mishandling this request will only return a `NOERROR` response for the first one and will return `NXDOMAIN`, `REFUSED`, `SERVFAIL` or some other error status for the second. | ||

| It is important to use a DNS server that handles this situation correctly since Home Assistant uses alpine for many of its containers. Alpine follows the DNS spec and will treat the entire domain as if it can't be resolved if it receives an error status for either query. Home Assistant will run into many unexpected issues in this situation, particularly around updates and installing software. |
