feat: add toJSON to ErrorFromResponse class (#1540)

## Description of the changes, What, Why and How?

Vitest [serializes
errors](https://github.com/vitest-dev/vitest/blob/v3.1.3/packages/utils/src/error.ts#L60-L62)
and our error instance keeps a ton of data (from Axios) which - when
serialized - pollutes test logs with unreadable messages (see
GetStream/chat#8211 QA runs for "before").


(it's way longer, see scrollbar)

after:

This needs to be copied over to video SDK as well.
