Fix syntax error in ids-check.yml workflow (#175629)

that the ids check workflow has a syntax error in it. After looking at
the workflow, it appears to be missing - on the uses lines. After this
change and having looked at the file in Githubs file editor, no syntax
error red lines are now appearing so this should fix it.
