Outdated dependencies

Konnichiwa Osamu.

I am using your library and have found that some of the dependencies are outdated.
My IDE shows that there are updates for three dependencies of the package.

github.com/goccy/go-json v0.10.0 -> v0.10.2
github.com/invopop/jsonschema v0.7.0 -> v0.12.0
github.com/stretchr/testify v1.8.2 -> v1.8.4

If there are no special reasons for not updating the version, it would be great to update them.

I also suggest adding a built-in GitHub feature called "Dependabot" which automatically informs repository owners about available updates. This feature saves me a lot of time for maintaining versions updated.

Arigato !

Hello, Osamu.
I see activity in your repositories, but for some reason you are not responding.
Are you supporting your libraries ?
