MarshallComponentsException Fix

[danialcheung]

Fixes AttributeError: module 'streamlit.components.v1' has no attribute 'components' by changing components.components.MarshallComponentException to components.custom_component.MarshallComponentException as found in the corresponding module for the Streamlit Repo.

Fixes #275

Please can this PR be approved?
This issue is preventing us from using recent versions of Streamlit.

I'm trying to use your branch @danialcheung. I added this to pyproject:

streamlit-aggrid = { git = "https://github.com/danialcheung/streamlit-aggrid.git", branch = "danialcheung-marshallcomponentsexception-fix-1" }

But I get:

StreamlitAPIException: No such component directory: '/poetry/.venv/roadway-IgtDOu2o-py3.11/lib/python3.11/site-packages/st_aggrid/frontend/build'

Traceback:
File "/home/backend/streamlit_server.py", line 9, in <module>
    from st_aggrid import AgGrid, GridOptionsBuilder, GridUpdateMode, DataReturnMode
File "/poetry/.venv/roadway-IgtDOu2o-py3.11/lib/python3.11/site-packages/st_aggrid/__init__.py", line 92, in <module>
    _component_func = components.declare_component("agGrid", path=build_dir)
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                      

Any ideas on how I can use your fork while this isn't merged?

@Ricardonacif Sadly I installed this over pip so I'm not familiar with running from source. Maybe try npm install inside the home directory and see if it builds the files?

I tried that, got a bunch of different errors :(
