docs: document custom domain TXT verification records

[mintlify]

Summary

Document the _acme-challenge and _cf-custom-hostname TXT records that the dashboard now displays and automatically verifies when you add a custom domain.

Changes

• Added a "Verification TXT records" section under "Configure your DNS" explaining the two TXT records, what they're for, and that the dashboard auto-checks their status.
• Updated TLS provisioning copy to reference Mintlify's automatic certificate flow instead of Vercel.
• Removed the outdated "Vercel verification" accordion.

Context

The upstream change adds automatic verification of custom-domain TXT records via DNS lookups, and surfaces the records and their configuration status in the dashboard. The existing custom domain page didn't mention these records, so users following the dashboard prompts had no documentation explaining what to add or why.

Note

Low Risk
Low risk documentation-only changes; no product code or runtime behavior is modified.

Overview
Adds a new Verification TXT records section to customize/custom-domain.mdx, documenting the required _acme-challenge and _cf-custom-hostname TXT records and noting the dashboard auto-checks their DNS status.

Updates TLS provisioning wording to reflect Mintlify’s certificate issuance flow (and that HTTPS is available after provisioning), and removes the outdated Vercel-specific verification accordion.

Redundant AccordionGroup wrapping a single Accordion element

Low Severity

After removing the "Vercel verification" accordion, the <AccordionGroup> now wraps only a single <Accordion>. In Mintlify, <AccordionGroup> exists to group multiple accordions together; a standalone <Accordion> renders fine on its own without a group wrapper. The <AccordionGroup> is now redundant and adds unnecessary nesting.
