Ignore 403 errors

[unixorn]

Description

Some sites forbid scraping from GitHub IPs, so treat a permission error for a page as it being present, otherwise we'd be getting a 404.

Type of changes

• Add/Remove/Update a helper script or git alias
• Add/Remove/Update link to an external resource like a blog post or video
• Plugin file updates - functions added here probably should be standalone scripts in /bin
• Text cleanups/updates
• Test updates

License Acceptance

• This repository is Apache version 2.0 licensed (some scripts may have alternate licensing inline in their code) and by making this PR, I am contributing my changes to the repository under the terms of the Apache 2 license.

Checklist

• I have read the CONTRIBUTING document.
• I have confirmed that the link(s) in my PR are valid.
• All new and existing tests pass.
• Any scripts added use #!/usr/bin/env interpreter instead of potentially platform-specific direct paths (#!/bin/sh is an allowed exception)
• Scripts added/updated in this PR are all marked executable.
• Scripts added/updated in this PR do not have a language file extension unless they are meant to be sourced and not run standalone. No one should have to know if a script was written in bash, python, ruby or whatever. Not including file extensions makes it easier to rewrite the script in another language later without having to change every reference to the previous version.
• I have added a credit line to README.md for any new scripts.
• If there was no author credit inside a script added in this PR, I have added one.
