Raise deploy ship timeout to 5 minutes

The deploy `ship` job is capped at `timeout-minutes: 1`, but pulling and
extracting the full-site archive, uploading the Pages artifact, and the GH Pages
deployment now total just over a minute as the site has grown (older deploys ran
~30s). A manual deploy of master hit the cap and was cancelled at the "Deploy to
GH Pages" step, so the build never went live.

Raise the cap to 5 minutes to give headroom.
