Update swagger

[WillGunn]

v10.1.1 of @apidevtools/swagger-parser (APIDevTools/swagger-parser@3c907d7) fixed an issue, adding support for oas3.0.4.
Currently this tool has v10.1.0 pinned and so passing in a openapi = "3.0.4" spec file causes this tool to error when it doesn't need to.

Please update the package.json and lock file to target v10.1.1 of the swagger-parser dependency to fix this issue.
