feat(nextcloud): Add new onlyoffice config options (#14698)

**Description**
<!--
Please include a summary of the change and which issue is fixed. Please
also include relevant motivation and context. List any dependencies that
are required for this change.
-->
⚒️ Fixes  # <!--(issue)-->

Adds additional config options for onlyoffice.

With the current setup, the connection may not work out of the box,
since Nextcloud and OnlyOffice will try to talk to each other using
their public FQDNs. In this case, the user will have to configure the
internal FQDNs manually from Nextcloud UI.
