v4.0.0

In scope of release we enable cache by default. The action won’t throw an error if the cache can’t be restored or saved. The action will throw a warning message but it won’t stop a build process. The cache can be disabled by specifying cache: false.

steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-go@v4
    with:
      go-version: ‘1.19’
  - run: go run hello.go

Besides, we introduce such changes as

• Allow to use only GOCACHE for cache
• Bump json5 from 2.2.1 to 2.2.3
• Use proper version for primary key in cache
• Always add Go bin to the PATH
• Add step warning if go-version input is empty
