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

Commencez par reproduire la commande signalée avec l’URL JSON OpenAPI liée, puis examinez le chemin de chargement et d’analyse de la source qui traite sa réponse text/plain. Le travail est terminé lorsque le client génère correctement depuis cette URL et que le comportement de fallback est couvert par un test de régression.
