Update links to the Telegram Bots (Support, GetBridges) across our support platforms
Telegram has changed the url of the bots (i.e https://t.me/@GetBridgesBot --> https://t.me/GetBridgesBot) and we need to accordingly update our documentation on RT, cdr.link, Forum and elsewhere. (Thanks to a translator and @emmapeel for spotting this!)
