pdfplumber verison 0.11.3 happen error "TypeError: 'type' object is not subscriptable"

[Akiramex]

When I use the latest pdfplumber verison 0.11.3. to run my program，the bug happen。

Traceback (most recent call last):

def _get_rows_or_cols(self, kind: type[CellGroup]) -> List[CellGroup]:
TypeError: 'type' object is not subscriptable

But when i use the version 0.11.2，the program can run nomal.

type[CellGroup] looks like python 3.9 syntax (https://docs.python.org/3.9/whatsnew/3.9.html#type-hinting-generics-in-standard-collections), I'd assume you see this bug on Python 3.8 (which the setup.py lists as compatible)

Thanks for flagging @Akiramex and for identifying the issue @andrekeller. Now fixed in v0.11.4.

After October 2024, I plan to end pdfplumber's support of Python 3.8, following the official EOL schedule, but happy to make this quickfix in the meantime.
