clean up spell config, extend contraindicated to include biological process, add mappings

[sierra-moxon]

• tru -> true
• add mappings to SEMMEDDB predisposes and predicts
• fix KEGG missing mapping and duplicate UMLS mapping on SmallMolecule
• extend the range of "contraindicated in" to include biological process to match definition
• added predicate mappings to increase|decrease|affect activity or abundance that were missing for the Tests asset conversion.

also include the infores and semmed schemas in the directory accessible by w3id config as they were missing
experimented with codespell config - it still does not seem to be processing typos in the YAML files.
