Better indent guides for Pug/Jade

[CS-Birb]

Your programming language(s)

Pug/Jade & Vue SFC (.vue files)

Expected Behavior

• In .vue files, Pug/Jade Support carries through to a nested document in between <template lang="pug"> and </template>, as the standard HTML/XML does.
• Pug support includes support for Rainbow indent guides

Current Behavior

• In .vue files, HTML in the <template> is recognised and handled as expected.
• Pug/Jade Support appears to be recognised only at the file level - A nested document as in between <template lang="pug"> and </template>,
• In pug files, Indent guides are the standard grey despite settings.

Code snippet for reproduce (for bugs)

Vue file

<template lang="pug">
  div
    h1 Level 1 Header
    h2 Level 2 Header
    div
      span Etc
      p
        | More content
        b Nested bold
        | Etc
</template>

<script lang="ts">
  import Vue from "vue";

  export default Vue.extend({
    name: "example"
  });
</script>

<style scoped>

</style>

Thank you greatly for implementing #897 - Has been a lovely addition to my daily workflow, and am happy to now be a pledger for this project.
Sorry to become "that pug-obsessed guy"

I will look into it in one week or two, The inline-document already supported for JSX, it should not be hard for Pug.
