Do not apply Drupal.Commenting.Deprecated.DeprecatedWrongSeeUrlFormat

[mglaman]

As a developer
I would like to @see a non-Drupal link

Right now you cannot use @see to link to other documentation in regards to a change. This is also required if something is marked as @deprecated. I should be able to link to product documentation on another site.

@mglaman this sounds like a bug in the Coder module. The DeprecatedWrongSeeUrlFormat warning is part of the DeprecatedSniff, which implies that it's only meant to apply to @see tags appearing adjacent to a deprecation tag. If you're seeing this warning outside of a deprecation, can you open an upstream bug with Coder?

This raises a somewhat thornier question: should we encourage projects that aren't Drupal modules to use Drupal coding standards? If Drupal decides that only documentation on drupal.org can be referenced by @see tags, is that a bug or a feature when applied to projects that aren't Drupal modules but want to follow the same coding standards?

Is still still relevant now that we have separate standards for non-Drupal PHP projects?
