cwltool --validate doesn't check for InlineJavascriptRequirement when it should

[sjaenick]

Hi,

cwltool 3.1.20230601100705

For a workflow with cwlVersion: 1.2 and some steps only executed conditionally via when, cwltool successfully validates the workflow even if InlineJavascriptRequirement is not specified.

Sample workflow e.g. at https://github.com/MGX-metagenomics/cwl/blob/master/metagenome-assembly-pipeline.cwl - cwltool --validate still reports success even if the InlineJavascriptRequirement is removed.
