No '@master' in the uses section of Readme example

[el-veee]

Hey I noticed in the README.md Usage example, in the build section, in the uses like, there is no @master.

e.g. as it is, it looks like uses: operatehappy/packer-github-action

The other sections look like uses: operatehappy/packer-github-action@master

Is the build section correct? Or should it be @master?
