[JavaScript] String.concat accepts any number of any values

[fartinmartin]

The current definition of the String.concat says it will:

converts the one or more given values to strings...

But, the type suggests a it only accepts a single string value:

Types-for-Adobe/shared/JavaScript.d.ts

Lines 1006 to 1011 in 6953648

	/**
	* If necessary, converts the one or more given values to strings.
	* Those values are concatenated with the original string, the result is returned. The original string is not effected.Returns the concatenated string.
	* @param value The values to be concatenated with the given string.
	*/
	concat(value: string): string

This PR updates the parameters to ...values: any[].

    ["array", 1, { two: "three" }],
    "string",
    function test() {
      return true;
