My proposal is suitable for this project

• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Link to the rule's documentation

Description

The allow option of this rule can be configured to allow spreading strings with { from: 'lib', name: 'string' }, but this does not cover string literals, and there is no way to specify things like "any string literal" using this option.

I propose that we add an option like allowStringLiterals in addition to allow (or make it possible to specify "any string literal" with TypeOrValueSpecifier), which allows spreading of just string literals.

Fail

let myStr: string = "String literals in this project is known to not contain grapheme clusters.";

[...myStr]; // not a string literal type, thus not covered by this option

Pass

[..."String literals in this project is known to not contain grapheme clusters."];

const myStr = "a string const";
[...myStr];
