build: update WinGet publish workflow to use env instead of --token (#467)

With the latest winget-create release, the preferred method for
providing the GitHub token in CI/CD environment is via the environment
variable `WINGET_CREATE_GITHUB_TOKEN`. Removed use of `--token` and
switched to environment variable. See https://aka.ms/winget-create-token
for details.
