Stylelint not catching quotes in function

[Tregonia]

Stylelint is not catching rules in SCSS functions.

To reproduce:

• Create the function below

// Get unit of number.
@function get-unit($value) {
  @return str-slice($value * 0 + "", 2, -1);
}

• Use the function to get unit of a number

Notice that the double quote do not trip the linter.

Could you provide a quick recommendation for addressing this, @Tregonia ?
