fix(bar_chart): data typing

[Oleksii14]

Original issue: apertureless/vue-chartjs#1058

Why would the default data point need adjustment, you are able to provide your own custom data types to chart.js:

import { Chart, ChartData } from 'chart.js';

var data: ChartData<'polarArea', {x: Date, y: {foo: boolean}}[]> = {
  labels: [],
  datasets: [{
    data: [{ x: new Date(), y: {foo: false} }],
  }],
};

var ctx = document.getElementById("myChart") as HTMLCanvasElement;
var myChart = new Chart(ctx, {
    type: 'polarArea',
    data: data,
});

You're right. The original issue should be resolved directly in the Vue.js implementation of the chart components. Thanks for the reply. I am closing this PR.
