Allow to override tag using `x-code-tag`

Allow to override tag as the grouping mechanism per endpoint using the 'x-code-tag' property on the operation

Is x-code-tag standard or used by another popular tool? Or should we use a name specific to this tool?

I think this will require tweaking the underlying pydantic attribute. Also, this needs an end-to-end test added to verify it works as expected.

i added e2e test for it i did not found something similar so x-code-tag is as good as any name IMO

I'm still not clear on when you'd want to add an extra attribute to override the module name instead of modifying the tags directly (if you can edit the OpenAPI document anyway)
