fix: only close tags in supported scope

[IgnaceMaes]

Addresses #17 for glimmer-js and glimmer-ts. Can be extended to support other language blocks like vue, etc.

const foo: Array<string>|;
                        ^ no auto closing of tag here
 
const bar = <template>
  <p>|
     ^ auto closing of tag as it's in a template
</template>
