Add sssom convert step to validate_mappings command
The validate-%
make command should look like this:
validate-%:
mkdir -p $(TMPDIR)
tsvalid $(MAPPINGDIR)/$*.sssom.tsv --comment "#"
sssom validate $(MAPPINGDIR)/$*.sssom.tsv
sssom convert $(MAPPINGDIR)/$*.sssom.tsv -o $(TMPDIR)/schema-$*.sssom.ttl
For an example see: https://github.com/mapping-commons/sssom/blob/master/project.Makefile#L26
