Fix for dynamically evaluated source code traceback And add test. This should close #14057

Remove no longer needed mypy note, mention darker/black versions (#14343) Fixes https://github.com/ipython/ipython/issues/14338 Thanks @s-kai273 for pointing out missing version info.

pyproject.toml (project.entrypoints, project.scripts): Define here (#14340) ... instead of in setup.py, setupbase.py Another step toward removing setup.py, as requested by @Carreau in https://github.com/ipython/ipython/pull/14327#pullrequestreview-1884755776

Remove no longer needed note about mypy and mention darker/black versions used on CI

pyproject.toml (project.entrypoints, project.scripts): Move here from setup.py, setupbase.py

Delay import from matplotlib_inline.backend_inline (#14330) Possible fix for #14329. With this change, the reproducers from the issue become: ```python $ ipython <snip> In [1]: import matplotlib.pyplot as plt; plt.set_loglevel("debug") In [2]: %matplotlib tk DEBUG:matplotlib.pyplot:Loaded backend TkAgg version 8.6. ``` It is still possible to call `matplotlib.pyplot.switch_backend` twice but only if you request `%matplotlib inline`, and the `switch_backend` is called with same correct backend twice. This isn't ideal but it doesn't cause any problems apart from being a little slower than necessary.

Retire commands `setup.py symlink`, `setup.py unsymlink` (#14327) Apparently introduced in #4473 (over 10 years ago), undocumented.
