[3.13] gh-129438: Update ``--enable-experimental-jit`` section with install requirements (GH-129450) (#129472) gh-129438: Update ``--enable-experimental-jit`` section with install requirements (GH-129450) Add a note to the `JIT` docs that building CPython with `JIT` requires Python 3.11 or newer.

Cross-compiling "just works", since the JIT is built for the host platform. The JIT can also be enabled or disabled using the `PYTHON_JIT` environment variable, even on builds where it is enabled or disabled by default.
