[Bug] no-disabled-tests reports non-test functions as disabled if their param starts with "x"

[rothsandro]

The vitest/no-disabled-tests rule reports a disabled test for upper1 and upper3. It looks like the rule detects functions with a param that starts with x and we call a function on that param.

test("foo", () => {
  const upper1 = (x: string) => x.toUpperCase();     // <-- reported
  const upper2 = (y: string) => y.toUpperCase();    
  const upper3 = (xy: string) => xy.toUpperCase();   // <-- reported
  const upper4 = (yx: string) => yx.toUpperCase();
  const upper5 = (a: string) => a.toUpperCase();
  const length = (x: string) => x.length;
});

The problem happens after updating to v1.1.18, it works fine in v1.1.17
