Update dependencies

[qarmin]

Some of dependencies are outdated like openapiv3 or openapi_utils - https://deps.rs/repo/github/matusf/openapi-fuzzer

Without updating, I'm unable to check if with glademiller/openapiv3#70 will fix my problems

Hi, thanks for the heads up. I know it's out of date. I keep it at that version because I need openapi_utils at the current version and it does not work with newer version of openapiv3. I plan to update the openapi_utils along with it openapiv3, but it requires a larger refactor.
