[Console] Add remote_indices to autocomplete overrides (#193403)

## Summary

Closes #188608 by adding
"remote_indices" to the Create or update roles API. I'm not adding
`remote_cluster` because it's not documented, and I don't know yet if
it's on purpose or not. As `remote_indices` was also missing from the
Elasticsearch specification, I opened
elastic/elasticsearch-specification#2915 too.
