validator-urls.csv

Fixing old data in 0box

• Create a new temp table filled with the data in the attached csv file. Let's call the table tmp_validator_urls
• Run the following query

UPDATE provider SET url = tmp_validator_urls FROM tmp_validator_urls WHERE tmp_validator_urls.id = provider.provider_id

This fix needs to be applied AFTER this PR is merged and deployed on mainnet sharders, otherwise it will be overwritten from the incorrect data coming from the sharders.
