Updated NOTICE file with new dependency information

Looks like MRs !20 (merged) and !21 (merged) brought in some dependency changes without updating the NOTICE. This includes the new dependencies.

The SnakeYAML and Elasticsearch removals are coming from GPL / MIT sections. I believe FOSSA database had these older versions miscategorized (common among multi-licensed libraries, since it is hard for FOSSA to know which license you would choose). Newer versions seem to have different choices.
