Run go mod tidy and create PullRequest on GitHub Actions

https://github.com/marketplace/actions/go-mod-tidy-pr

This is inspired by circleci-bundle-update-pr

Now, Dependabot officially supports go mod tidy.

https://github.blog/changelog/2020-10-19-dependabot-go-mod-tidy-and-vendor-support/

So this action is deprecated.

If you configure Pull Request build on GitHub Action, builds doesn't trigger when go-mod-tidy-pr creates Pull Request.

https://docs.github.com/en/actions/reference/events-that-trigger-workflows#triggering-new-workflows-using-a-personal-access-token

The workaround is one of the following.

1. Use GitHub App Token instead of secrets.GITHUB_TOKEN (RECOMMENDED)
   • Required permission: Pull requests (Read & write)
2. Use personal access token instead of secrets.GITHUB_TOKEN
3. Use CI other than GitHub Action on Pull Request build
