Does not compile for Golang

[pkpfr]

The 2.9 version (perhaps others) does not compile for Go.

There are duplicate type declarations for TicketType and TicketTypes.

One of the duplicates needs an x-go-name attribute to allow api-codegen to be able to generate working Go code.

Similar error when using oapi-codegen:

error generating code: error generating type definitions: error generating code for type definitions: duplicate typename 'TicketType' detected, can't auto-rename, please use x-go-name to specify your own name for one of them
exit status 1

Hi @pkpfr and @billinghamj - we are doing an audit of the spec now and will address these issues, thank you for flagging
