Upgrade oapi-codegen dependency

[maticmeznar]

Description

Because of the way old versions of oapi-codegen were structured, they pull in a lot of transitive dependencies like Iris and Gin web frameworks, needlessly increasing the dependency tree for any project importing oapi-codegen generated code, including this Typesense client.

Would it be possible to upgrade the dependency?
