Remove all PyPI installation documentation

Removed all references to installing wipeit from PyPI throughout
the documentation and workflows.

Changes:
- README.md: Removed PyPI installation sections, kept only source install
- .github/workflows/release.yml: Changed GitHub release body to use git clone
- DOCS/CHANGES.md: Updated release automation description
- DOCS/CI-CD.md: Removed PyPI publishing from features list
- Makefile: Removed PyPI upload instructions

Installation is now exclusively from source via:
  git clone https://github.com/cscortes/wipeit.git
  cd wipeit
  uv sync

All distribution packages remain local only.
