Workaround for bug #59450.
Related to PR #59441.
Locally test runs about 90 seconds.
However on the bazel-test CI the test frequently runs over 5 minutes.
Extending the timeout as a work-around to ease the rerun problem.
As @mikedanese notes :-
The Validate calls to the vendored go-openapi library are which make the test slow:

We should probably do more perf and send a patch to upstream.
