Getbridgesbot on telegram - proposal to correct the inicial announcement

Currently when the new user opens the bot they see:

To get Tor bridges, just ask for bridges sending the command /bridges

I offer to change that message as /bridges command no longer works.

To get Tor bridges, just ask for bridges sending the command /obfs4 for obfs4 bridges and /webtunnel for webtunnel bridges

(if it fits the character limit)
