Won't generate client for JSON formatted API with tabs

Describe the bug

Running

openapi-python-client generate --url https://raw.githubusercontent.com/wikimedia/mediawiki-extensions-Wikibase/e45d4f725e25a95ec2b034238fd3736f19053a16/repo/rest-api/specs/openapi.json

gives me the error

Error(s) encountered while generating, client was not created

Invalid YAML from provided source: while scanning for the next token
found character '\t' that cannot start any token
  in "<byte string>", line 2, column 1:
        "openapi": "3.1.0",
    ^

This is a follow-on to this old bug https://github.com/openapi-generators/openapi-python-client/issues/488 which got fixed in https://github.com/openapi-generators/openapi-python-client/commit/b01db03349eb83e4c3ffdd1cc70f7eb2a9c6dae8 . It appears the fix doesn't quite work because github doesn't serve JSON files with the expected content-type (curl with -v gives me "< content-type: text/plain; charset=utf-8").

OpenAPI Spec File
I was trying to generate a client for this code

Desktop (please complete the following information):

• OS: Ubuntu 20.04.6 LTS running under Windows 11
• Python Version: 3.8.0
• openapi-python-client version 0.17.0

Additional context
I think the correct fix ought to be to fall back to JSON parsing in the event of YAML parsing failure (or else a flag to specify?). I'm not sure why the mimetype isn't being guessed right

Bắt đầu bằng cách tái hiện lệnh đã báo cáo với URL JSON OpenAPI được liên kết và kiểm tra đường dẫn tải và phân tích cú pháp nguồn xử lý phản hồi text/plain của URL đó. Hoàn tất khi client tạo thành công từ URL này và hành vi fallback được bao phủ bởi một bài kiểm thử hồi quy.
