partial merge #16327: scripts and tools: Update ShellCheck linter
1ac454a3844b9b8389de0f660fa9455c0efa7140 Enable ShellCheck rules (Hennadii Stepanov)

Pull request description:

  Enable some simple ShellCheck rules.

  Note for reviewers: `bash` and `shellcheck` on macOS are different from ones on Ubuntu.
  For local tests the latest `shellcheck` version 0.6.0 should be used (see #15166).

# This simple script checks for commits beginning with: scripted-diff:
# If found, looks for a script between the lines -BEGIN VERIFY SCRIPT- and
# -END VERIFY SCRIPT-. If no ending is found, it reads until the end of the
# commit message.
# The resulting script should exactly transform the previous commit into the current
# one. Any remaining diff signals an error.
