ci: bump actions/checkout to v5

[defangdevs]

actions/checkout@v4 is a Node 20 action; GitHub Actions is deprecating Node 20 runners (https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/). This bumps to v5, which uses Node 24 and removes the deprecation warning.

Summary by CodeRabbit

• Chores
  • Improved the reliability and security of automated release and testing processes.
  • Updated workflow configuration to use a fixed, verified version of the source checkout action.
  • Disabled unnecessary credential persistence during automated tests.
