v3.40.0

• added: cd-into-temporary-worktree value for machete.traverse.whenBranchNotCheckedOutInAnyWorktree git config key (suggested by @andrii0lomakin)
• changed: when a branch is behind remote (needs a pull), git machete traverse now skips rebase,
  just as it did already when branch is diverged from & older than remote (suggested by @lsierant)
• fixed: when git machete traverse failed on a rebase within a worktree,
  in certain cases the warning message about changed directory didn't show up (reported by @lsierant)
