Improve all taxonomies (CSET and GMF) CSV export

[pdcp1]

Part of #3023
On top of #3030

This PR changes the way that we export taxonomies CSV files.
Now it iterates through all taxonomies on the taxa collection, dynamically generating a CSV file based on the fields of each taxonomy and the data from the classifications collection.

Based on the current data, it will produce these 5 CSV files:

• classifications_CSETv0.csv
• classifications_CSETv1.csv
• classifications_CSETv1_Annotator-1.csv
• classifications_CSETv1_Annotator-2.csv
• classifications_CSETv1_Annotator-3.csv
• classifications_GMF.csv

Anywhere I can see this working?

@cesarvarela Yes, I just updated the PR description with the testing instructions.

Looks good; my only question is if the array notation is expected for lists in CSV files:

I think it is usually comma-separated and without quotes.

@cesarvarela It's ready for another review. Now it convert Array of values into comma-separated values as you suggested.
An example of CSV exports is here https://pub-daddb16dc28841779b83690f75eb5c57.r2.dev/backup-20240910002252.tar.bz2
