[Wallet Redesign] Provide texts for Beginners Guide

@startailcoon @sschiessl-bcp I need one of you to provide texts what are we going to display on Beginners Guide - https://github.com/bitshares/bitshares-ui/issues/2984
For the following steps:
- Deposit / Withdraw (requires your approve, already designed as you can see on a pic)
- Exchange
- Business
- Governance
- Worker Proposals

@sschiessl-bcp I remember you want to merge Governance & Worker Proposals but I think we have enough cool people who use bitshares and ready to propose some good work for us. That's why I decided to put it as separate tab but TBD.
