[Maps] remove region/coordinate-maps visualizations from sample data

[nreese]

Fixes #71143

PR replaces region map visualizations with vega visualizations in sample data. These provide examples of how to make maps with vega with labels and tooltips

this is really good imho

fwiw, I would add an example of graduated colors too, since it's something the old coordinate-map vizzes did as well.

e.g.

 scales: [
    {
      name: gridSize
      type: linear
      domain: {
        data: table
        field: doc_count
      }
      range: [
        50
        1000
      ]
    }
    {
      name: bubbleColor
      type: linear
      domain: {
        data: table
        field: doc_count
      }
      range: ["#ff7f0e","#e7ba52","#17becf"]
    }
  ]
  marks: [
    {
      name: gridMarker
      type: symbol
      from: {
        data: table
      }
      encode: {
        update: {
          fill: {
            scale: bubbleColor
            field: doc_count
          }
          size: {
            scale: gridSize
            field: doc_count
          }
          xc: {
            signal: datum.x
          }
          yc: {
            signal: datum.y
          }
          tooltip: {
            signal: "{flights: datum.doc_count}"
          }
        }
      }
    }
  ]

Great idea. I updated logs map with color scale
