Suggestions:

1. Change the path to additional package-lock.json: jmix-dependencies/additional/npm/X.Y.Z/package-lock.json
2. Support ability to get last existing 'fix' version package-lock.json - we need to build archive for each fix version (X.Y.Z) but in most cases there are no changes within single minor version.
   So we don't want to add the same file for each fix version and make new release of Deptool each time.
   We need to support both X.Y and X.Y.Z variants of version directory - it should check specific fix version (X.Y.Z) first, then if not found - last existing fix versionX.Y.Z. If none of them found - it should check minor version X.Y which should be mandatory to be added on release.
   E.g. if we request resolve dependencies for release 2.5.0 - it should check versions 2.5.0 -> 2.5 (till the first match). For version 2.5.2: 2.5.2 -> 2.5.1 -> 2.5.0 -> 2.5.
   Java dependencies currently check only minor version (we expect no changes within minor version) but it wold be nice to implement the same for them too.
3. Need to add info about it to documentation: how to get, where to add and what's gonna happen.
