[bisq-network/bisq] Add logo to README (PR #6145)

[Christoph Atteneder]

I just recognized that we also need to remove the Travis build icon and replace it with the Github Actions svg.
I think `[![Actions Status](https://github.com/bisq-network/bisq/workflows/Build%20Bisq/badge.svg)]`
should do the trick. Could you please add this to your PR as well?
