title: In Apexcharts (react-apexcharts), specifying stackType: "100%" gives the error Type 'string' is not assignable to type '"normal" | "100%" | undefined'
body: <p>I'm trying to create a simple stacked, 100%-type bar chart as per the docs:</p>
  <p><a href="https://apexcharts.com/vue-chart-demos/bar-charts/stacked-100/" rel="nofollow noreferrer">https://apexcharts.com/vue-chart-demos/bar-charts/stacked-100/</a></p>
  <p>However, whenever I try to specify a stacked bar type as a stackType of 100%:</p>
  <pre><code>options: {
              colors: ['#9B51E0'],
              background: '#FFAFFC',
              title: {
                  text: 'Weekly Progress',
                  style: {
                      fontSize: '16px',
                      fontWeight: 'normal',
                      fontFamily: 'IBM Plex Sans, sans-serif',
                      color: '#53599A'
                  }
              },
              chart: {
                  id: &quot;basic-bar&quot;,
                  stacked: true,
                  stackType: &quot;100%&quot;
              },
              xaxis: {
                  categories: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
                  position: 'bottom',
                  labels: {
                      show: true,
                      style: {
                          colors: ['#53599A', '#53599A', '#53599A', '#53599A', '#53599A', '#53599A', '#53599A'],
                          fontSize: '12px',
                          fontFamily: 'IBM Plex Sans, sans-serif',
                          cssClass: 'apexcharts-xaxis-label'
                      }
                  }
              },
  </code></pre>
  <p>I get the error:
  No overload matches this call....
  Type 'string' is not assignable to type '&quot;normal&quot; | &quot;100%&quot; | undefined'.</p>
  <p>Even though apexchart.d.ts defines it as:</p>
  <pre><code>stackType?: 'normal' | '100%'
  </code></pre>
