(tlg0019.tlg001.perseus-grc3) non existent file?

Looks like this file was bumped twice. So [grc3 in the Cite Collections](https://catalog.perseus.org/cite-collections/versions/search?utf8=✓&field_type=version&search=tlg0019.tlg001.perseus-grc) is redundant.

See [main issue](https://github.com/PerseusDL/canonical-greekLit/issues/1392) here.
