text: Title: Dialogs created by `Dialogs` should bind `Enter` key to `OK` button
  Body: When creating a popup dialog asking the user for an input, the dialog already nicely auto-focuses into the textbox, allowing immediate keyboard input. However, then pressing the Enter key does nothing. I would have expected it to to be the same as pressing the left "OK" button. It would be very useful to have that so that users don't have to use the mouse to press that button.
  
  Example:
  ```robot
  *** Settings ***
  Library    Dialogs
  
  *** Test Cases ***
  Get Device Number
    [Documentation]  Grab the device number from the user
    [Tags]           production
    ${dev_num_usr}=  Get Value From User  Input the number of the device (on the label)  invalid
  ```

  I'm on Ubuntu Budgie 22.04.
