Classify git commits and use only manual commits in co-change analysis

[JohT]

🚀 Feature

• Classify git commits:Git:Commit nodes now have the new properties:

  • isMergeCommit: more than 1 parent
  • isBotAuthor: author contains [bot]
  • isMavenCommit: commit message stars with `[maven'
  • isAutomatedCommit: Is either isBotAuthor or isMavenCommit
  • isManualCommit: is neither isBotAuthor nor isMavenCommit

• Use only manual commits for co-change analysis: Now, only manual commits are taken into account for co-changing files analysis.

⚙️ Optimization

• Update python dependencies seaborn, optuna, neo4j
