all tests are failing with similar

E   requests.exceptions.ProxyError: HTTPSConnectionPool(host='raw.githubusercontent.com', port=443): Max retries exceeded with url: /datacite/schema/732cc7ef29f4cad4d6adfac83544133cd57a2e5e/source/json/kernel-4.3/datacite_4.3_schema.json (Caused by ProxyError('Unable to connect to proxy', NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f87bab74170>: Failed to establish a new connection: [Errno 111] Connection refused')))

I think it might be worth just shipping copies of desired verion(s) of datacite serializations right in here, in particular since we are referencing a specific to commit version.

dandi-cli versions failing to install with

ERROR: Package 'dandi' requires a different Python: 3.8.18 not in '>=3.9'

since here we have not yet dropped 3.8 and in dandi-cli already did...

[djarecka]

i'm wondering if we really want to keep all the version from these repositories, or decide on one that we want to match. Or perhaps we want to create our own?

[yarikoptic]

we had to do diff archaeological expedition so I thought to accumulate them all in one common space. They are relatively lightweight so I saw no reservation from keeping them all.

Moreover, with exposing version in the code we could try one or another easily and consistently across versions.
