Per tag generation doesn't generate correctly when using .json

[perkinsjr]

To Reproduce

1. Using a OpenAPI file that is in JSON format. (https://api.unkey.dev/openapi.json)
2. Use default generation which is per tag
3. A single file will be generated versus file for each tag.

Current vs. Expected behavior

Expected to see a file per tag when generating but saw one large file instead.

Oops it is a docs mistake, it should be file by default. You can pass “tag” directly
