Function levenshteinDistance

levenshteinDistance(str1, str2): number
Calculates the Levenshtein distance between two strings.

[!NOTE] The complexity of this function is O(m * n), where m and n are the lengths of the two strings. It's recommended to limit the length and validate input if arbitrarily accepting input.
Parameters
- str1: string
  The first string.
- str2: string
  The second string.
Returns number
The Levenshtein distance between the two strings.
Example: Usage
```
import { levenshteinDistance } from "@std/text/levenshtein-distance";
import { assertEquals } from "@std/assert";

assertEquals(levenshteinDistance("aa", "bb"), 2);
```
