chore: remove deprecated devDep for root-ca script (#2342)

## Description

Noticed in reviewing our renovate dashboard that `@types/csv-parse` is
noted as deprecated now (types directly in the `csv-parse` package):
https://www.npmjs.com/package/@types/csv-parse.

This PR removes it and adds an extra action for addlicense on the
generated CAs.
