Fix warning on SAP BTP deployment (HDB) npm warn config production Use `--omit=dev` instead.

[agiguere]

All our SAP BTP deployment to Cloud Foundry from CAP project issue this annoying warning

INFO executing the "npm install --production" command...
npm warn config production Use --omit=dev instead.

I reported it to SAP via an incident and they told me this

I figured it's not the CAP tools, but the mbt tool that creates the npm install --production commands for MTA modules of type hdb.
I will dispatch the ticket to the respective team.

thanks
