CI needs further fixing

[tvami]

Describe the bug

The env variable is deduced to be

  LDMX_VERSION_FILE=/home/runner/work/ldmx-sw/ldmx-sw/VERSION

or

  cat: /home/runner/work/ldmx-sw/ldmx-sw/VERSION: No such file or directory
  Traceback (most recent call last):
    File "/home/runner/work/ldmx-sw/ldmx-sw/./.github/actions/validate/compare.py", line 195, in <module>
      compare(sys.argv[1], sys.argv[2], sys.argv[3], sys.argv[4])
  IndexError: list index out of range

in https://github.com/LDMX-Software/ldmx-sw/actions/runs/13064853937/job/36455888351?pr=1551

To Reproduce

For example see
https://github.com/LDMX-Software/ldmx-sw/actions/runs/13061170684/job/36445294614

Desired behavior

Move it one directory up

Maybe the issue is that GITHUB_WORKSPACE changes for the different CIs

Thinking more, I think this will break the gold generation CI, otherwise this
https://github.com/LDMX-Software/ldmx-sw/pull/1550/files
would have failed

The problem is not with the placement of VERSION, the problem is how we distribute the gold to the various validation jobs.

We copy the gold over from trunk, but then only tar-ball up the install and the .github directory. We need to include VERSION in the tar that is then shipped to the other jobs.

ldmx-sw/.github/workflows/pr_validation.yml
