Don't show API key in release summary

[hugovk]

Right now, run_release.py prints a summary at the start, including the API key:

❯ .venv/bin/python run_release.py --repository ../cpython --ssh-user me --release 3.14.0a0
Release data:
- Branch: main
- Release tag: 3.14.0a0
- Normalized release tag: 3.14.0
- Git repo: ../cpython
- SSH username: me
- python.org API key: me:123456789012345678901234567890123456789
- Sign with GPG: False

Let's mask it:

❯ .venv/bin/python run_release.py --repository ../cpython --ssh-user me --release 3.14.0a0
Release data:
- Branch: main
- Release tag: 3.14.0a0
- Normalized release tag: 3.14.0
- Git repo: ../cpython
- SSH username: me
- python.org API key: me:************************************789
- Sign with GPG: False

Let's not show it:

❯ .venv/bin/python run_release.py --repository ../cpython --ssh-user me --release 3.14.0a0
Release data:
- Branch: main
- Release tag: 3.14.0a0
- Normalized release tag: 3.14.0
- Git repo: ../cpython
- SSH username: me
- Sign with GPG: False
