Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

Fix a case where one inaccessible plugin search path stops the whole search and prevents latter paths from being scanned. Remove a preliminary `Stat` call that verifies whether path is an actual directory and is accessible. It's unneeded and doesn't actually check whether the directory can be listed or not. `os.ReadDir` will fail in such case anyway, so just attempt to do that and ignore any encountered error, instead of erroring out the whole plugin candidate listing.
