Based on the answer from this topic - stepped-color-shading-in-highcharts-doughnut-chart.

Wrapping bubble's prototype:

var bubbleProto = Highcharts.seriesTypes.bubble.prototype;

  bubbleProto.axisTypes = ['xAxis', 'yAxis', 'colorAxis'];
  bubbleProto.optionalAxis = 'colorAxis';
  bubbleProto.colorKey = 'y';

  Highcharts.wrap(bubbleProto, 'translate', function(proceed) {
    proceed.apply(this, Array.prototype.slice.call(arguments, 1));

    Highcharts.seriesTypes.heatmap.prototype.translateColors.call(this);
  });

Since Highcharts v7.2.0 you can add coloraxis module and use it for almost all series types:

Highcharts.chart('container', {
    ...,

    colorAxis: {
        minColor: '#c6e48b',
        maxColor: '#196127'
    }
});
