dev-zig/zls: add unkeyworded 0.14.0-r1 with improvements

Changes in diff order:
- remove github as the second HOMEPAGE (it's already in remote-id)
- simplify & automatize ZIG_SLOT assignment
  - also moved comment there so it's clearer
- simplify SRC_URI assignment
- use ZIG_SLOT in SLOT
- introduce minimum_runtime_zig_version
- unquote DOCS contents
- remove obsolete pkg_postinst
