Duplicate DNSLink TXT record about distributions

[cewood]

Seems related to API changes that DNSimple seems to have made a some point, and we discovered as part of https://github.com/protocol/bifrost-infra/issues/2814 and ipfs-shipyard/dnslink-dnsimple#21

I've removed duplicate DNS TXT records (for both .io and .tech), and the issue is resolved.

I'm assuming a hiccup on the dnsimple end, but if we have this problem again, we need to investigate the https://www.npmjs.com/package/dnslink-dnsimple angle, maybe API changed, and we need to update that tool.

It's happening again, I have no permissions to remove it.

We'll need to also update https://github.com/ipfs-shipyard/js-dnslink-dnsimple then (which after a npm-check-updates is very out of date 😱 )

Asked @olizilla to give me and @hacdias publishing rights to the NPM package, but JS necromancy can be a time sink.
Switching to already working and way more deterministic GO version may be more stable, given how finicky JS packages run via npx can be.

I'll open a PR later today. Update: see #1055
