(PUP-11764) Add nginx module fixture

Adds a subset of the files from the pmtacceptance-nginx module from the test
forge. The github action `actions/checkout@v3` will by default convert NL to
CRNL on Windows, unless disabled in git config. This commit disables text
mode (-text) for those files in .gitattributes. This is necessary, because
future commits will need to `puppet module changes` to compare the modules'
files on disk against the `checksums` hash in metadata.json.
