Remove support for passing custom GitHub token through the GITHUB_TOKEN environment variable. It should be passed to the `github-token` input instead.

If we have this "they have to match if both are specified" rule - shouldn't we kinda also enforce that in other subactions that use github-token?

I think this is more for compat to push migration, so eventually in the next major we can remove this and we don't have to mind about GITHUB_TOKEN anymore.

throw new Error(
'The GITHUB_TOKEN environment variable is set and does not match the "github-token" input. ' +
'Please pass the custom GitHub token to the "github-token" input and ' +
"remove the GITHUB_TOKEN environment variable to avoid conflicts.",
);
}

// If the user needs to change the cwd, set `working-directory` in the step instead
