Rename GraphQL .gitignore template

The .gitignore file is unable to load via classpath resource from the
graphql node server resource directory (for unknown reasons). Before
this change, the missing template would fail silently.

A .gitignore file may exist in other directories and load as expected.
Added a default .gitignore to _common as a fallback so as not to break
any custom generators which may also be failing silently.
