no issue
- updates usage of `htmlRelativeToAbsolute` to avoid unnecessary duplication of "home" url fetching (the UrlUtils instance already has that information)
no issue
- updates `@tryghost/url-utils` following an internal refactor of the package
- renames `makeAbsoluteUrls` to `htmlRelativeToAbsolute` to better reflect what the function is doing
- renames `getBlogUrl` to `getSiteUrl`
- updates UrlUtils test stubbing util to work with a class
- fixes use of invalid port numbers in tests (max port number is 65535, any higher is an invalid URL that will error with some parsers)
- a yaml parser error can only be fixed by the user uploading a file, therefore it should be a 4xx, not a 5xx error
- an amp parser error indicates the amperize module is unable to handle a genuine case, and needs to be fixed at the code level
