Equalize Open Application keywords from RPA.Excel.Application, RPA.Desktop.Windows, RPA.Outlook.Application

So they all would return app instance and would be easier to use them together. Something like:

*** Settings ***
Library    RPA.Excel.Application    WITH NAME    Excel
Library    RPA.Desktop.Windows      WITH NAME    Windows
Library    RPA.Outlook.Application    WITH NAME    Outlook

*** Tasks ***
Manipulate application
    ${outlook_id}    Outlook.Open Application
    ${excel_id}      Excel.Open Application
    ${word_id}       Windows.Open Application   Word
    Windows.Switch To Application  ${outlook_id}
    Windows.Minimize Dialog    ${excel_id}
