Refactor/improve AreaPageContainer to support 2-column layout

[vnugent]

Both climb and area page use a 2-column layout defined by the following classes

• area-climb-page-summary
• area-climb-page-summary-left
• area-climb-page-summary-right

We should improve AreaPageContainer container to support left and right child component.

Todo

• [ ] Improve AreaPageContainer to support a left and right child component

• [ ] Replace the divs in climb and area pages with the new component

• climb page: https://github.com/OpenBeta/open-tacos/blob/develop/src/pages/climbs/%5Bid%5D.tsx

• area page: https://github.com/OpenBeta/open-tacos/blob/develop/src/app/area/%5B%5B...slug%5D%5D/page.tsx
