[pgAdmin4][RM#3002] To fix the indentation issue in query tool editor

[Murtuza Zabuawala]

Hi,

PFA patch to fix the issue where Tab key was not working as expected in
query tool editor.

Steps to reproduce:
1) Type any multiline sql/text.
2) select the complete sql by pressing Ctrl+A.
3) Press Tab key multiple times, you will see the problem in code
indentation.

Please review.
