+    - **Description**:  Checks if the package name is suspiciously similar to any package name in a predefined list of popular packages. The similarity check incorporates the Jaro-Winkler distance and considers keyboard layout proximity to identify potential typosquatting.
+    - **Rule**: Return `HeuristicResult.FAIL` if the similarity ratio between the package name and any popular package name meets or exceeds a defined threshold; otherwise, return `HeuristicResult.PASS`.

    - Ensure it is assigned to the `problog_result_access` string variable, otherwise it will not be queried and evaluated.
    - Assign a rule ID to the rule. This will be used to backtrack to determine if it was triggered.
    - Make sure to wrap pass/fail statements in `passed()` and `failed()`. Not doing so may result in undesirable behaviour, see the comments in the model for more details.
