Home page that communicates what people need to know

Acceptance Criteria

• [x] #1829
• [x] #1830
• [x] #1831
• [ ] #1832
• [x] TBC: https://github.com/geeksforsocialchange/PlaceCal/issues/1818 (this might be functionality on the homepage or it might be an action link to what is currently the "Find my PlaceCal" page - depends how much space it ends up taking and what else is on this home page once we wireframe.

Implementation notes

• NEEDS INFO: Make the concise description. Agree how long it should be in the first instance and we can use lorem.
• NEEDS INFO: What can I do here? Decide which actions we want to include and what the action looks like. Probably needs a wireframe.

How might we: e.g. As a person wanting to start my own PlaceCal instance, it is clear that I can and how to start that process. (Note this is currently the Join link, but we might want to make it explicitly one of the actions) See #1819
