exa’s website has incorrect links to latest version, man files, completions files and Ubuntu package

The website "the.exa.website" indicates there are packages on apt for more than just Ubuntu gorilla, but when searching the package repo, only the gorilla package is found.

The manual install steps provide the man page link as "https://raw.githubusercontent.com/ogham/exa/master/contrib/man/exa.1" which is invalid.
