Add `Persona's` from the Bitcoin UX Research by Patricia Estevao into `Getting to know your users`

[pavlenex]

@pavlenex nice, I wasn't aware she had even posted her research results on the web (was only aware of the repo).

Ideally, we could integrate her results more closely into the guide. A good starting point could be to identify key quotes from each persona and insert them into relevant pages. Also, the Getting to know your users page is currently relying on a made-up persona, maybe this could be refreshed with a persona Patricia identified?

Looking at what we have atm, and how we might approach the navigation re-structure, I think I may close this issue if we decide to add Personas and User Journeys sections as a part of the User research section. Thoughts?

I'd like to do this one as a first issue.

This is my work in progress that may help you @Mogashni https://www.figma.com/file/znxW3KaKZXRAfO4RPAZ3h9/Bitcoin-UX-Persona?node-id=0%3A1, but feel free to use your own visuals, this is just me trying to cut down on text and visualise it.
