Single file component can contain only one <script> element

[swliu920322]

when i make a README.md, i add

_当前计数为： {{ count }}_
<button @click="count++">点我！</button>

// next code origin from components
<basic-table />

<script lang="ts">
import { defineComponent, ref } from 'vue';
export default defineComponent({
  setup() {
    const msg = 'Markdown 中的 Vue';
    const count = ref(0);
    return {
      msg,
      count,
    }
  }
})
</script>```

when i add a sfc file from components catalog, i get a error like title,
i think my custom sfc file also has script tag,
 i get two script tags from .temp/pages/README.vue;
how can i add my custom component to the md file;
