DRAFT: Add documentation for how to use the table filtering section of scicat

[nickcrawford1]

This MR adds a documentation to for the Scicat table and column filtering as well as saving data. It is intended as a user guide on how to navigate and operate the filtering options along with information about what will return.

Thanks so much for putting in the time to do this. There has been an initial start to the documentation on the dashboard but I think this goes further. It would be good to amalgamate the two docs.

I would say that the structure of this should be:
/docs/datasets/DashboardTableEditing.md

The current docs can be found here:
/docs/login/Dashboard.md

I would suggest that we keep the section on the Landing Page in /docs/login/Dashboard.md, but move the content on table filtering to /docs/datasets/DashboardTableEditing.md along with the new content on saving data.

@LAShemilt I've made adjustments to the structure and taken repeated elements out of each document to avoid confusion. I think separating the files is the way to go to ensure each element is clear for the users but let me know if you're not a fan of this.

Hi Nick, LGTM just some small changes to the wording and typos. Once applied this can be merged.
