feat(website): generate metadata docs from config

[anna-parker]

resolves ##2375, pathoplexus/pathoplexus#245, #3013

pathoplexus preview URL: https://preview-standardize-metadata-docs.pathoplexus.org/docs/concepts/metadataformat

Summary

1. Creates a metadata description table for the docs directly from the values.yaml config to avoid duplication and future errors, also allowing different input fields for each organism.
2. Generates a tsv with all metadata fields users can input with their descriptions
3. Adds a desired metadata parameter to annotate metadata fields that we would like users to upload if possible.

Future work

• After metadata definitions and guidance fields have been reviewed in Pathoplexus it would be good to update them here as well.
