LCDocument import error due to TYPE_CHECKING condition

[ ] I have checked the documentation and related resources and couldn't resolve my bug.

Describe the bug
When I run https://github.com/explodinggradients/ragas/blob/main/docs/howtos/integrations/llamaindex.ipynb in google colab, I get the following error:

NameError Traceback (most recent call last)
in <cell line: 2>()
1 # generate testset
----> 2 testset = generator.generate_with_llamaindex_docs(
3 documents,
4 testset_size=5,

Expected behavior
A clear and concise description of what you expected to happen.

Additional context
In ragas/testset/synthesizers/generate.py, LCDocument is imported under a TYPE_CHECKING condition, and the value of TYPE_CHECKING is false.
