[RFC/PoC 2/5] Documentation Bundles: ignore artifact files from creating doc bundles

[Philip Oakley <philipoakley@iee.email>]

The Git documentation contains many examples that can be prepared as
repository bundles for users to clone and explore without any language
or translation confusions between the written word and intended code.

There are also a large number of example repositories in the t/ test
system can can also be exposed to users to highlight the critical
distinctions tested therein.

These documentation bundles will be prepared ar part of the test system.
Start by ignoring those parts which will be considered build artifacts,
the GIT-BUNDLE-DIR, and the `.bndl` bundle files themselves.

The artifacts themselves will later be manipulated by the `make` elements
of the documentation system.
