FieldList - migrate from ODH and document API

[nicolethoen]

The code for this component currently lives athttps://github.com/opendatahub-io/odh-dashboard/blob/main/frontend/src/components/FieldList.tsx

This new components should be built using PF6.

A PF6 version of this component lives in the current PF6 migration POC PR: opendatahub-io/odh-dashboard#3038

The API of the new component should match the API of the component in RHOAI.
We can improve a11y, right-to-left language support, replace deprecated components under the hood, or generally clean up the implementation, as long as the API works in RHOAI.
