Repro

{
  "rules": {
    "@typescript-eslint/<rule>": ["<setting>"]
  }
}

// your repro code case
try {
} catch (error) {
  throw new Error(`Could not foobar: ${error.message}`)
}

Expected Result
Should not error, because any is assignable to string the same way that a string literal type is. (This would be a case though for no-implicit-any #791 , but that's not the goal of this rule)

Actual Result
"Invalid type of template literal expression."
