RED can't identify robocorp/rpaframework libraries as expected

[bbartok76]

I've started to use the RPA Framework of Robocorp with RED and I've experienced the following issue with the RPA.Excel.Files library:

• the expected way to import an RPA library and accepted by the robot during execution:
  Library RPA.Excel.Files
• the accepted way to import in RED is without the RPA prefix:
  Library Excel.Files

The documentation for the RPA.Excel.Files is here: https://rpaframework.org/libraries/excel_files/
I experienced the same with other RPA libraries.

If I try to import the library with the RPA prefix I get the following error message after discovery:
Additional info: RED was unable to find class 'RPA.Excel.Files' inside 'file:///C:/dev/eclipse-workspaces/ta-robot-salesforce/.venv/Lib/site-packages/RPA/Excel/Files.py' module.

Version information:

Eclipse version: 2020-09 (4.17.0)
Robotframework version: 3.2.2
RED version: latest (no version information available)
