Metabolomnics technology type

We have two technology types for metabolomics:

• LC-MS-based metabolomics: @mmattano used (https://github.com/bigbio/proteomics-sample-metadata/pull/680) in the PR the EDAM ontology NT=LC-MS-based metabolomics;AC=EDAM:3172 we should move this term to PSI-MS or PRIDE ontologies.
• NMR metabolomics: Similar to the previous term, we should move it into PSI-MS or PRIDE ontologies. The main reason is because we use these two ontologies to handle data properties (comment).

To be discussed.
