test: updated gitSync commands file (#33633)

RCA: There are many unused commands within gitSync.js file

Solution:
Checked the gitSync in both CE and EE repository and we are removing
those commands which are not used in any tests as part of cleanup
activity
Equivalent EE PR: appsmithorg/appsmith-ee#4280
