Update mention of DuckDB in README (#7101)

* Update mention of DuckDB in README

This commit makes the following changes to the README regarding the mentions of DuckDB:

- Removes the mention of the `duckdb` R package, which is not a `dplyr` backend, but rather a package purely for connecting to and querying a DuckDB database, like the dozens of similar packages that are specific to various database programs, and would likely be used with `dbplyr`.

- Corrects the broken link for the `duckplyr` package from https://duckdblabs.github.io/duckplyr/ to https://duckplyr.tidyverse.org/

- Changes the language of the mention of the `duckplyr` package to be consistent with the rest of the backend packages, following this order: name of the backend R package, use case, and underlying technology that the backend translates `dplyr` code to.

* Tweaks
