Add options to @typescript-eslint/no-unused-expressions

[yangmingshan]

I think we should set all @typescript-eslint/no-unused-expressions options to true.

{
  '@typescript-eslint/no-unused-expressions': [
    'error',
    {
      allowShortCircuit: true,
      allowTernary: true,
      allowTaggedTemplates: true
    }
  ]
}

Why? Those are all anti-patterns.

[yangmingshan]

The first two maybe, but even tagged templates?

[sindresorhus]

Why would you use a tagged template without using it?

[yangmingshan]

Oh, I didn't notice, sorry.
