Changes

• Update to tauri v2.2.0
• User-agent is now set to an OS-specific UA
• User-agent now reflects actual Webview2 version on Windows
  • Apparently in super rare cases, if this wasn't implemented, it would cause your account to be flagged for potential spam. Dorion only ever had one report of this happening, lol
• Clicking a notification now focuses Dorion
• Re-adds Windows 7 notification behaviour
• Use shelter's new(ish) "injector" pattern, which should prevent some confusion
  • This basically just means that Dorion plugins show up in the plugins list with an info icon stating "This plugin is part of Dorion"
  • This also means Dorion settings show up slightly higher in the list
• Rework a fair amount of notification behaviour
• Many rsRPC fixes and improvements
• Fix top bar when using light mode (#273 from @luximus-hunter)
• Fix safemode
• Fix window not remembering position (#272)
