Remove Bazel dependency for simpler local development

- Update build-dependencies.sh to use Go instead of Bazel for Prysm
- Update testnet.sh to use Go-built binaries
- Remove Bazel installation from CI workflow
- Update README to reflect Go 1.23+ requirement only
- Simplifies setup for developers and CI environments
