* Fixup the spec string for sys.executable

The previous spec string was:

    namespace(name='cpython', cache_tag='cpython-313', version=sys.version_info(major=3, minor=13, micro=0, releaselevel='candidate', serial=1), hexversion=51183809, _multiarch='x86_64-linux-gnu')313-True

When it was supposed to be:

    cpython313-64

Fixes https://github.com/tox-dev/tox/pull/3325/files#r1718230254
Fixes https://github.com/tox-dev/tox/pull/3325/files#r1718246292

Adds tests for a new method.

* Make the new method private

* Silence the linter, this is a test for a private method

The error was:

    tests/tox_env/python/test_python_api.py:314:12: SLF001 Private member accessed: `_python_spec_for_sys_executable`
