bump github actions, use node 24

[tijmenbruggeman]

Workflows gave a warning:
Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: actions/cache@v4, actions/checkout@v4, actions/setup-node@v4, actions/upload-artifact@v4, nick-fields/retry@v3
As we are being forced to run on node 24 anyway, might as well update the actions.

• actions/cache to v6
  • https://github.com/actions/cache
  • went from v3 (setup action) & v4 (integration tests) to v6.
  • actions/cache@v3...v6.1.0
  • biggest change is node version which is now on node24 (lts). v6 also migrated to ESM.
• actions/setup-node to v7
  • https://github.com/actions/setup-node
  • went from v4 to v7.
  • actions/setup-node@v4...v7.0.0
  • v5/v6 also added automatic caching, but only when package.json has a packageManager field. We set cache: 'npm' explicitly, so nothing changes for us.
• actions/upload-artifact to v7
  • https://github.com/actions/upload-artifact
  • went from v4 to v7.
  • actions/upload-artifact@v4...v7.0.1
  • v7 adds an opt-in archive: false for unzipped single-file uploads, which we don't use. We are going to use this later though as we are now uploading the artifiact after a release but this contains all our development files.
• nick-fields/retry to v4
  • https://github.com/nick-fields/retry
  • went from v3 to v4.
  • nick-fields/retry@v3...v4.0.0
  • node version only
• softprops/action-gh-release to v3
  • https://github.com/softprops/action-gh-release
  • went from v2 to v3.
  • softprops/action-gh-release@v2...v3.0.3
  • only node version as well

Summary by CodeRabbit

• Chores
