[BUG] JAR version hardcoded to 0.3.0-SNAPSHOT

[cedricvidal]

Describe the bug
The JAR version is hardcoded to 0.3.0-SNAPSHOT and doesn't reflect the actual version of the release.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://github.com/microsoft/NubesGen/releases/tag/v0.17.0
2. The jar name is nubesgen-cli-0.3.0-SNAPSHOT.jar when it should be nubesgen-cli-0.17.0-SNAPSHOT.jar

Expected behavior
The jar name should reflect the version of the release
