title: Suppress Angular Language Service VSCode extension's "strictTemplates in angularCompilerOptions" notification
body: <p>Since we upgraded our codebase to Angular 11 I get this message in VSCode:</p>
  <blockquote>
  <p>Some language features are not available. To access all features, enable <code>strictTemplates</code> in <code>angularCompilerOptions</code>.</p>
  <p>Source: Angular Language Service (Extension)</p>
  </blockquote>
  <p>With a link to &quot;Open tsconfig.json&quot;, like this:</p>
  <p><a href="https://i.stack.imgur.com/RrCLd.png" rel="noreferrer"><img src="https://i.stack.imgur.com/RrCLd.png" alt="visualization of above described text" /></a></p>
  <p>I'm looking forward to enabling this and enjoying the new feature. But I want to set time apart to do and test this. For now, the popup in VSCode keeps coming up all the time, which is annoying and distracting.</p>
  <p>How can I (for now) suppress this message, preferably for my current workspace?</p>
