Add Support for DocC in Xcode 13 (#1091)

* Add support for DocC

DocC "files" are actually folders `.docc` appended to the name, but Xcode 13 treats them differently. Therefore, we need to exclude them from the normal BuildPhase.

Resolves #1089

* Add tests for DocC

Expanded an existing test to include .docc support.

Also added a .docc catalog to the Test Project.

* Update changelog.md

* Update changelog.md to get the correct PR Link
