* Check if the SemVer is greater than the range.
*
* @example Usage
* ```ts
* import { parse, parseRange, greaterThanRange } from "@std/semver";
* import { assert } from "@std/assert";
*
* const version1 = parse("1.2.3");
* const version2 = parse("1.2.4");
* const range = parseRange(">=1.2.3 <1.2.4");
*
* assert(!greaterThanRange(version1, range));
* assert(greaterThanRange(version2, range));
* ```
*
* @param version The version to check.
* @param range The range to check against.
* @returns `true` if the semver is greater than the range, `false` otherwise.
