Add-ons [021] XenForo WebSockets 2.1.2

• Fix: window.ws.event.on does not work correctly on XenForo 2.3
• Fix: X-WebSockets-Page-Uid header not passed to AJAX requests on XenForo 2.3

• Fix: Incorrect channel matching when there is a dot in the channel name (for example, Forum.{id} could match ForumTypers)
• Fix: Issue with channel subscription when using Pusher.com
• Fix: No icon in add-ons list

• This update is supposed to fix an annoying bug that has existed since the add-on release: incorrect display of online users in expansions such as Real-Time Chat and XenForo Messenger
• Implemented an elegant solution for updating the csrf token and connecting to the websocket server when restoring a page from the back-forward cache: this should improve the connection when restoring a tab in a browser on mobile devices and help avoid the "Security error..." error.
• XenForo 2.3 support
• Name pattern feature for channels
• XF.Echo and XF.EchoManager now are deprecated, use window.ws.echo and window.ws.manager instead
• Updated soketi config parameters generation format to more user-friendly
• Removed some permission checks in the broadcast controller to ensure websockets work correctly in different situations
• Minimum PHP version now is 8.1
