Clarify skipped "Install packages (Ubuntu)" step

- Slightly reword and reformat the block comment.

- Run two commands instead of using `&&`, since with `shell: bash`
  (inherited as the default as specified at the workflow level),
  the actual shell command invoked for script steps includes `-e`,
  so the script would still immediately fail if the first command
  fails.
