Clarify dependencies and versions

[kachick]

It looks like some dependencies are being used, even without thinking about Go and TypeScript.

Some examples are...

• gitbook (deprecated - https://github.com/pankona/hashira/issues/870)
• gcloud
• protoc
• golangci-lint
• goreleaser
• yarn
• dprint (In planning phase - https://github.com/pankona/hashira/pull/871)

They are assumed to use both local and CI, but basically no version definiton exists both local and CI. (.tool-version exists, but it was not used in CI) It has some problems

• It is hard to setup environment for contributors
• #836
• #837
• #854

Some problems are fixed and prevented, but some still exist. I suggest to provide a version manager that can manage versions with the config file. I used nix, asdf/rtx, docker. But I'm happy with any candidate that can handle all the current dependencies and easily track versions and CI integrations.
