Use github actor id instead of bot name to avoid renaming issues (#740)

This PR modifies the GitHub Actions workflow to use the GitHub actor ID
instead of the bot name. This change helps avoid issues related to
renaming the bot, ensuring that the workflow continues to function
correctly even if the bot's name changes.
 See renovatebot/renovate#37842.
