In page.NewOutputFormat, we take an output.Format f and use it to create a page.OutputFormat. If the format is canonical, we assign the final OutputFormat's Rel to "canonical" rather than using f.Rel. However, this leads to unexpected behavior for custom output formats, where a user can define a "rel" for a format via the config file. For example, the standard for "humans.txt" files requires using rel="author" in HTML "link" elements. Meanwhile, humans.txt is usually the only format used for its content. As a result, for Hugo configurations that define a humans.txt custom output format, Hugo will render "link" elements to content in this format with rel="canonical," rather than "author" as required by the standard. This commit changes page.NewOutputFormat to check whether a given format is user defined and, if so, skips assigning Rel to "canonical," even if isCanonical is true. Fixes #8030
