Do not include composer.lock in distribution

The composer.lock entry is clearly missing export-ignore.

Although it doesn't harm to have this in the exclude export, it doesn't harm either to have it in the export.
Composer will look for a lock-file at project level and will not use the lock file of dependencies.

Thanks for this minor fix.

Exactly the same can be said about any other line in .gitattributes 😉
