Typos involving (/n) in docs

[Jennoit]

A typo involving character (/n) appears in several areas of the docs - mostly in UI CSV import sections. For example "The CSV file uses Linux/Unix style end-of-line characters /n" at https://www.accesstomemory.org/en/docs/2.6/admin-manual/maintenance/cli-import-export/#digital-object-load-task

It should be \n for Linux/Unix end of line.
