[Feature Request] UI folder icon, Docs and plugins

• Addition of a small folder icon to the left of the "Play" button, so that the folder is easily found and opened, this would help for integrations into Steam or Playnite etc.
• It would also be nice to specify where these files were installed in the first place.
• Helpful if there was some documentation on how to setup/use this Launcher in the OpenRCT2 docs It is not mentioned at all. It was easy personally, but many fear the unknown. It looks to be a nice way to keep OpenRCT2 upto date. I will make a fresh guide on steam soon.
• Perhaps upgrade this tool to install, check and update the plugin versions too.
• If there are any CLI arguments such as --update or --play OpenRCT2. They would also be useful for Playnite to Steam automation.

Start by splitting the request into the launcher UI, OpenRCT2 documentation, plugin version handling, and CLI automation. Review the area containing the Play button, the linked OpenRCT2 Windows installation page, the OpenRCT2 plugin site, and any existing launcher arguments. Done requires an agreed scope and acceptance criteria for the selected request; the issue currently combines several independent features.
