Scheduled Workflow Assumes That MODEL Repo Name is MODEL-configs Without -configs

[CodeGat]

This assumption has done fairly well for us so far, but a repo that breaks that assumption is coming - namely, https://github.com/ACCESS-NRI/access-om3-wav-configs.

The assumption comes in here:

model-config-tests/.github/workflows/config-schedule-2-start.yml

Lines 117 to 118 in 7934e2d

	# model is just the config repo name without the '-configs' bit, so split it below with bash param expansion
	model=${config%-*}

Double check that we don't repeat that in other workflows (for example, .github/workflows/config-pr-*.yml somewhere).
