Update dependency get-port to v5

Editor assessment

The subject identifies the exact dependency and its new major — get-port to v5 — satisfying clarity without guesswork. The chore(deps) classification is correct, the imperative verb is clean, and there is no trailing punctuation or ticket junk. No body is needed for a mechanical update and none is penalized; no footer is required because the bump breaks nothing in the declaration. The message is accurate and complete for its type, held below exemplar only because it offers no note on what the port-utility change affects, which is the accepted limit for automated bumps.
