Problem Statement

Add "easy win" pre-commit rules to help to catch simple errors and reduce whitespace differences in PRs as well.

PR Actions - What was done

• Added "easy win" pre-commit rules:
  • end-of-file-fixer
  • trailing-whitespace
  • check-yaml
  • check-json
  • pretty-format-json
  • check-merge-conflict
  • check-symlinks
  • detect-private-key

How was this change tested

• Ran test suite.
• Ran coverage checker.
• Ran learnosity-sdk-assessment-quickstart with local build.
• Ensured that the Github CI action was present when PR was opened and that it was blocking if failing.

Note for reviewers
These are the key files that were modified / added:

• .github/workflows/ci.yml
• .pre-commit-config.yaml
• ChangeLog.md
• setup.py

All other files were modified according to the pre-commit hook rules (basically removal of trailing white spaces, additional of blank line at the bottom of every file and fixing typos in comments). These changes do not affect any logic or behaviour.
