Update documentation links within detectors

[arturoBeccar]

Description

Make changes in every detector to ensure that the linked documentation in the help field points to the detector's documentation in docusaurus.

For example:

For assert-violation we should replace:

       name: "Assert Violation",
        long_message: "Assert causes panic. Instead, return a proper error.",
        severity: "Medium",
        help: "https://github.com/CoinFabrik/scout-soroban/tree/main/detectors/assert-violation",
        vulnerability_class: "Panic",

For

       name: "Assert Violation",
        long_message: "Assert causes panic. Instead, return a proper error.",
        severity: "Medium",
        help: "https://coinfabrik.github.io/scout-soroban/docs/detectors/assert-violation",
        vulnerability_class: "Panic",
