Update getting-started.rst about ExceptionGroup.
The ExceptionGroup class is only available in Python 3.11 and later versions. If you're using an older version of Python, that's why you're seeing this NameError.
pytest already depends on exceptiongroup on those Python versions:
https://github.com/pytest-dev/pytest/blob/f373974707f57a0b28d12563e4d03c7cd54c70d9/pyproject.toml#L51
So the only reason why you'd get an error there is a broken setup of some sorts. @kmoonn could you elaborate what the motivation for this change is?
I don't understand the wording of this change. "... that's why you're seeing this NameError" - this implies a NameError that has already been mentioned somewhere, but there's no such earlier mention in getting-started.rst. This looks like a response copied out of context from an issue or an online community?
