refactor(etls): add all fields for DEVCO ETL - EUBFR-245

[kalinchernev]

PR description

Add fields are added, I've tried to follow this logic:

• SimpleValueField describes what has been discussed in the ticket about conventions. Targets mapping of single-value fields.
• TypedValueField is adding field and type on top of SimpleValueField. Targets mapping of multi-value fields.
• Other fields, which I could tell up front to be generic enough, I haven't prefixed with devco_, i.e. comments.
• Fields with obvious/known types, i.e. dates, I have formatted as ISO dates.

QA Checklist

When you add a new ETL/producer, please check for the following:

• Ensure the ETL has been correctly setup following the guide in services/ingestion/etl/README.md
• There is at least 1 sample record.json and 1 unit test with a jest snapshot for the result of the transform function of the ETL.
• Ensure there is (flow/jsdocs) documentation in the transform function
• Generate the necessary documentation pages for the new ETL by yarn docs:md
