function resolveTxt
Usage in Deno
```typescript import { resolveTxt } from "node:node__dns--promises.d.ts"; ```
resolveTxt(hostname: string): Promise<string[][]>
Uses the DNS protocol to resolve text queries (`TXT` records) for the `hostname`. On success, the `Promise` is resolved with a two-dimensional array
of the text records available for `hostname` (e.g.`[ ['v=spf1 ip4:0.0.0.0 ', '~all' ] ]`). Each sub-array contains TXT chunks of
one record. Depending on the use case, these could be either joined together or
treated separately.
Promise<string[][]>
