Quotes in Content-Type cause syntax errors

Describe the bug
Running openapi-python-client generate --path api.yml on the input file below fails with:

Generating /tmp/example-client
Error(s) encountered while generating, client was not created

ruff failed

example_client/api/default/put_object.py:34:62: SyntaxError: Simple statements must be separated by newlines or semicolons

Quotes in the Content-Type should be escaped so that the generated result is legal Python code.

Reproduisez l’échec avec openapi-python-client generate --path api.yml en utilisant l’exemple OpenAPI de l’issue, puis retracez l’endroit où la valeur de Content-Type devient l’affectation générée de headers. C’est terminé lorsque les paramètres Content-Type entre guillemets produisent du Python valide et que la génération s’achève sans l’erreur de syntaxe Ruff signalée.
