[Feature]: Nextcloud Integration

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Summary

Nextcloud is a suite of client-server software for creating and using file hosting services. It is enterprise-ready with comprehensive support options. Being free and open-source software, anyone is allowed to install and operate it on their own private server devices.

Integration would be a great add on to this platform.

### Why should this be worked on?

I run many servers that all have nextcloud as a remote access way of accessing them. They typically have other DB's or other resources that would go along with it. If Appsmith integrated nextcloud, that would make it so you only need one service for all of our needs instead of many services.
