remark-lint-double-link

Checks only duplicate URL, which helps to get rid of duplicates with the same link names or with different ones. The main policy is not to duplicate links to the same resources

<!-- Invalid -->

[link-1](http://link-1)
[link-2](http://link-1)

<!-- Valid -->

[link](http://link-1)
