Refactor Neo4j Dockerfile RUN instruction

[vibhatha]

Refactor the RUN instruction in deployment/choreo/development/docker/neo4j/Dockerfile to be more efficient and correct.

Issues identified in PR #422 discussion:

1. Redundant Package Installation: wget, unzip, and neo4j are likely already installed or can be optimized.
2. Unnecessary Variables: GITHUB_REPO, VERSION, ENV_NAME are redundant aliases for environment variables.
3. Incomplete Permissions: chown is missing /var/lib/neo4j/run and chmod -R 755 is missing.
