v3.25.3

• fixed: -y option in git machete traverse automatically sets --no-edit-merge flag, to retain behavior when the update=merge qualifier is set (contributed by @gjulianm)
• fixed: push=no and slide-out=no qualifiers now work in git machete advance now
• fixed: rebase=no qualifier now works in git machete slide-out
• improved: in git machete github create-pr/gitlab create-mr, check whether base/target branch for PR/MR exists in remote, instead of fetching the entire remote
