chore(deps): upgrade oapi-codegen

[andig]

Signed-off-by: andig [email protected], Follow-up to #387

Proposed Changes

This PR upgrades oapi-codegen to v2 and uses the new, trimmed runtime dependencies. The result is a big reduction of indirect dependencies in go.mod/go.sum and hence module download size.
