Bug Report

The linter that looks for large (>2^53) literals is not taking the numeric separators into account, resulting in it firing for very large numbers that are still in range (because of the added characters in the literal as a string).

e.g. For 18! (factorial) which is <2^53 (https://www.wolframalpha.com/input/?i=2%5E53-1+%3E+18%21).

💻 Code

const OK_FACT_18 = 6402373705728000;
const FLAGGED_FACT_18 = 6_402_373_705_728_000;

console.log(OK_FACT_18 === FLAGGED_FACT_18); // true

🙁 Actual behavior

Lint flagged the literal 6_402_373_705_728_000 with ts(80008).

🙂 Expected behavior

It shouldn't be flagged.
