The GitHub Actions runner redirects the stdout and stderr console
outputs and, now that twister properly invokes the Colorama module
initialisation function, the color output is disabled when running the
twister in the CI.
This commit adds the `--force-color` option when invoking the twister
so that the ANSI color escape sequences are output even when the output
is redirected by the GitHub Actions runner (note that the web console
properly displays the color escape sequences).
