update runs to checkout@v4 to use node20 since node16 is deprecated

Purpose/implementation Section

What scientific question is your analysis addressing?

1. As in V15 download and release notes (1/2) #554 and V15 subset files (2/2) #555, there is a persistent issue with the CRANIO module in that it appears that disk space is being exhausted. I am attempting some cleanup steps per the comments here.

2. I am pre-emptively updating to actions v4 which uses node 20 per the warning:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v3. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

What was your approach?

I remove all swap files, all old docker images, cache, unused packages prior to each analysis run.
