Input:

const foo = html`<p>test
</p>`;

Output:

const foo = html`
  <p>test</p>
`;

Expected behavior:
I would like a way to disable HTML template string formatting for a js/ts file, but I still want to format the file using Prettier (I just want the template strings to be treated as regular template strings rather than being formatted as HTML). In other words, I would like a way to disable the function here:

Other than using // prettier-ignore for every single template string, I do not think there is currently any way to do this.

My use case is creating test cases for an editor extension that provides autocomplete for HTML; so I want the tests themselves to be formatted as TypeScript, but I don't want to have Prettier format the HTML inside the template strings. Basically, something like htmlWhitespaceSensitivity: "ignore" but that only applies for template strings (I also have Vue files that I want to format).
