if you want RDI to create the db you still need to provide the RDI password to use
not sure if you always have to specify use_exisiting_rdi=false

I've added some text to say that you should set use_exisiting_rdi=false because I figure it won't do any harm. We can remove this in the future if it isn't necessary.

Use this if RDI database is using TLS or mTLS

Done. Also, I've commented these props out in the example TOML file (TLS/mTLS props are also commented out in the config.yaml example here: https://redis.io/docs/latest/integrate/redis-data-integration/ingest/data-pipelines/data-pipelines/#the-configyaml-file).
