Update: Pydantic V2

[opendansor]

Update Pydantic from V1 to V2. Some of the changes between V1 and V2 have breaking impacts, and our tests will need to be adjusted to reflect those changes.

You may want to use https://docs.pydantic.dev/latest/migration/#code-transformation-tool , while it won't solve everything it will be a good starting point.

Getting a number of errors when I run the tests locally. Not sure why.

Hey Dan, all looks good, but I did run bump-pydantic --diff bittensor/ to check, and I got this:

@thewhaleking I have addressed the Pydantic bump change.
