BUG: drep_info uses diferent field names for mainnet

[fallen-icarus]

Describe the bug
On preproduction and preview networks, the drep_info endpoint returns meta_url and meta_hash field names. However, on mainnet, these same fields are called url and hash.

Expected behavior
The field names should be exactly the same across the networks.

We're unfortunately forced into a bit of a rush with version releases, due to software version and fork dates coming out.
We were close to mark v1.2.1 release before and had it geared up on preprod, but since then - preview went through a fork, base version requirements changed of underlying components, and we're now in process of finalizing v1.3.0 (that you see on preview). You can track v1.3.0 status here.

While we are running preview , it is in a changing state. We did a put a note around unavailability of preview network here , we should be able to mark a release in a couple of days to update preview/preprod and then schedule for mainnet with finalized release notes.

It isnt how we'd like to operate releases, but have had to adapt as a domino-effect

Preview and Preprod are now updated - with mainnet update expected on 29th Nov, please check out release page
