REVISION SUMMARY
  Add twin commands for `gj` and `gk` for usage with standard
  arrow keys.
  
  BUG: 418486

TEST PLAN
  1. Open document with large sentences, that span across multiple visual lines in Kate and use `gj` and `gk` commands in normal mode to move inside a line.
  2. Use `g<down>` and `g<up>` commands - the result must be the same, as using `gj` and `gk` commands.
  3. Repeat the same for `visual` mode.
