okify regtests loses spec files

[braingram]

During downloading results okify uses a "--flat" option:

jwst/jwst/scripts/okify_regtests.py

Lines 110 to 114 in 57f6148

	args = list(
	['jfrog', 'rt', 'dl']
	+ [f"{ARTIFACTORY_REPO}/*_GITHUB_CI_*-{build_number}/*{suffix}"]
	+ ['--flat']
	)

which results in overwriting "spec" files for tests with matching names. When multiple tests fail that share the same name this results in only 1 of the failures being okified.

For example, this run:
https://bytesalad.stsci.edu/ui/repos/tree/General/jwst-pipeline-results/2024-11-20_GITHUB_CI_Linux-X64-py3.12-1006
when run with okify_regtests results only allows okifying 2 instead of 3 failures.
