✨ Add matrix integration (#1046)

* Added Matrix integration node

* fix: Improve code quality and add new operation

- Changed operation names to match casing (all camelCase)
- Ordering operation names to be alphabetical
- Creating a read all operation to fetch all messages from a room
- Added node subtitle

* fix: add element index so that expressions work on multiple items

* feature: added possibility to upload and send media to Matrix

- Also replacing Promises.all() + Array.map() For a regular for as it messes up ordering

* refactor: merging upload + send Media in a single action

* refactor: improved code quality and endpoints

- Removed sync entirely as a better way to retrieve messages is now
implemeented
- Added rooms dropdown to operations
- Added option to paginate or retrieve all room messages
- Removed option to upload media from text contents. Only files are
accepted now
- Room members has bem moved from the Rooms resource to a standalone
with Get All operation

* ⚡ Small improvements

* ⚡ Added filters to get messages

* ⚡ Minor improvements to Matrix-Integration
