This change is in service of forthcoming tests for the "JSON modules"
language proposal [1]. Verifying the semantics of that proposal requires
modules whose source text is not valid ECMAScript; this change updates
the guidelines for contributing and interpreting tests so that such test
material can be handled consistently.
Differentiating JSON files with a distinct file name suffice will assist
consumers which require special handling of such files (e.g. web
browsers).
Change the pattern used to designate "fixture" files so that it may be
applied to files used for JSON modules.
Increment the project version number to alert consumers of this change
in interpreting instructions.

This script is intended to identify common test file formatting errors
prior to their acceptance into the project. It is designed to support
future extensions for additional validation rules.
