Describe the bug

The "Provider Features" table is too wide; users don't naturally see the right-most columns

This page: https://docs.dnscontrol.org/getting-started/providers

To Reproduce
Steps to reproduce the behavior:

1. Go to https://docs.dnscontrol.org/getting-started/providers
2. You can't (without scrolling) see the right column.
3. When you do scroll, you don't see the row heads (provider names).

Expected behavior
Users should always see the row headers.

Some ideas:

• Replace the rtype columns (ALIAS, CAA, HTTPS, LOC, NAPTR, PTR, SOA, SRV, SSHFP, SVCB, TLSA, DS, DHCID, DNAME, DNSKEY) with a single column that lists the names of the supported records: A, MX, CNAME, LOC, PTR, TLSA.
  • The list should be a fixed-width, and word-wrap.
  • The list doesn't have to list records that all providers support: A, MX, CNAME
• Alternatively, make a 2nd table that just lists which record types are supported.

DNS Provider

• n/a
