svelte/no-useless-mustaches breaks on string literals containing `{}`

[ottomated]

Before You File a Bug Report Please Confirm You Have Done The Following...

• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.

What version of ESLint are you using?

9.21.0

What version of eslint-plugin-svelte are you using?

3.0.0

What did you do?

Configuration

import js from "@eslint/js";
import svelte from 'eslint-plugin-svelte';

export default [
  js.configs.recommended,
  ...svelte.configs['flat/recommended'],
];

Example: <code>import {'{ db }'} from '$lib/db'</code>

What did you expect to happen?

eslint-plugin-svelte should detect that the string literal contains curly braces, and therefore should be left untouched.

What actually happened?

Error:   61:39  error  Unexpected mustache interpolation with a string literal value  svelte/no-useless-mustaches

--fix:

Example: <code>import {db} from '$lib/db'</code>
                       ^~ Cannot find name db.
