Remove CIRRUS_CLONE_DEPTH.

I do not see any pkg-descr file. Please add one.

I am not a hard blocker here.

No. I have added the variable in HEAD. So from python 3.11 it is part of official python so no need to include this on python 3.11. What I did was:

  .  if ${PYTHON_REL} < 31100
  PY_EXCEPTIONGROUP=      ${PYTHON_PKGNAMEPREFIX}exceptiongroup>=1.1.1:devel/py-exceptiongroup@${PY_FLAVOR}
  PY_TOMLI=       ${PYTHON_PKGNAMEPREFIX}tomli>=2.0.2<3:textproc/py-tomli@${PY_FLAVOR}
* PY_TYPING_EXTENSIONS=   ${PYTHON_PKGNAMEPREFIX}typing-extensions>0:devel/py-typing-extensions@${PY_FLAVOR}
  .  endif

So PY_TYPING_EXTENSIONS will only be populated when python version is less than 3.11. And this is the exact case for at least this port. The pyproject.toml at least says that this is required only when python is less than 3.11. There are other ports where this is not the case and py-typing-extensions is mandatory and this variable should not be used.

I have tested and it works as intended.
