docs: link release to features page, update install instructions

- Release notes now link to docs/index.md features page and use
  absolute GitHub URLs for each feature doc.
- Add Install with Kernel Flasher section to release body (two heredoc
  blocks patched).
- README: remove 📜 Old Build Scripts and kernelsu.org install guide,
  replace with Install with Kernel Flasher steps (AnyKernel3 ZIP +
  Kernel Flasher / PixelFlasher).
