Set default token to `github_token` input parameter

[ybiquitous]

Hi there,

In this issue, I suggest making the github_token input parameter optional by setting the default token (secrets.GITHUB_TOKEN or github.token). The reason is that people can use this action with less configuration code.

https://github.com/reviewdog/action-rubocop/blob/bc5455ef2cd8f9e77232dc19c79bc0e450df8ed3/action.yml#L5-L7

For example, the change would be like this:

 github_token: 
   description: 'GITHUB_TOKEN' 
-  required: true
+  default: ${{ github.token }}

@mgrachev Thank you so much! 🎉

In addition, it would be very nice if other reviewdog actions could support the optional github_token parameter as well. 😄
