test: fix test file extensions and inputs for repositories (actions#161)

This pull request fixes the file extension for two test files that were
incorrectly named. This caused them not to be tested. A new test has
been added to ensure all test files have the correct extension.

This also fixes a bug in some tests where `repositories` inputs included
the repository owner. The owner has been removed from these inputs and
the snapshots have been updated.
