Create help dialog component

[whoabuddy]

We should create a general component that we can use with each page to provide context specific help information.

I think a pop up modal paired with a well placed help icon would be ideal, so it doesn't take up space unless clicks and pops up with relevant information.

E.g.

TIP: stick to simple, singular tasks and minimal tools to choose from. Build complexity through chaining atomic actions. 🤔

Do we want a modal/dialog or a tooltip?

modal could either be a new provider (if we want to make it reusable) or something we drop in on each page.
tooltip would be more lightweight, no provider needed.

modal would be a little more mobile friendly, since it would respond to click events. tooltips are usually just hover activated.
