1.0.0-rc6 - Patch content-type override doesn't take effect

[impatient]

Describe the bug
Override of content type via middleware does not take effect. Had to use work around listed here.

#1499

** Client Version **
1.0.0-rc6

** Server Version **
1.28.11

To Reproduce
Attempt to set StrategicMergePatch using middleware on the 1.0 client

Expected behavior
The middleware to take effect.

** Example Code**
nullplatform/k8s-lease-lock@6b189fd#diff-d8eee3b9c50488b328e4b9805b642354ccbaefadf361cbd9bd763925ed61ebeaR50

Wrapped in authMethods as a workaround. As mentioned in linked ticket.

Environment (please complete the following information):
Node 20.11

Additional context
Other ticket closed as not planned. Would you welcome a PR with documentation on this as a workaround or add it to the examples? Also, the case of Content-Type on header seemed to need to match exactly. Assume all issues are due to the generator, but might be worth it to expose a wrapper for middleware that hides this or at least some documentation.

Likely issue: OpenAPITools/openapi-generator#14549

Not sure how often people will run into this, but wanted visibility that it was still an issue that people were running into.

I reopened #1499 and I'm going to close this issue in favor of that issue.

We'd definitely welcome a PR to fix this. The generator team is usually very responsive to fixes in the generator.
