add_path is deprecated!

[ghost]

I get this:

Error: Unable to process command '::add-path::/bin' successfully.
Error: The `add-path` command is disabled. Please upgrade to using Environment Files or opt into unsecure command execution by setting the `ACTIONS_ALLOW_UNSECURE_COMMANDS` environment variable to `true`. For more information see: https://github.blog/changelog/2020-10-01-github-actions-deprecating-set-env-and-add-path-commands/

Change looks like: echo "$GITHUB_WORKSPACE/bin" >> $GITHUB_PATH. I shall see if I can make a PR for you.
