Add KB article on increasing file uploader limit

[snehankekre]

This PR adds a KB article on how to increase the upload limit of st.file_uploader in apps deployed to Streamlit Cloud. The solution is to set the appropriate config option in a global config file and upload said file to the app's GitHub repo.

This article was inspired by this forum thread.

Feels like the answer could be #1 or #2 here...you could either make a .streamlit folder, or put a config.toml file at the top level of the repo. I wonder if Cloud has a preference on which to say.

You're right! I completely overlooked option 2. I've seen repos that use option 2 as well. Will run it by Cloud and make changes to this PR.

When deploying to Streamlit Cloud

@randyzwitch AFAIK to be used, a config.toml file has to exist within a .streamlit/ folder. That folder should exist at the top level (root) of the repo, regardless of the location of the app app.py.

If the app is in a folder dir/app.py, the config file should be .streamlit/config.toml, not dir/.streamlit/config.toml.

To verify, I created a this repo and app:

• app.py and .streamlit/config.toml are within dir/
• Notice how the app does not use the custom (dark) theme defined in the config.
• It picks up the theme only when .streamlit/config.toml is moved out of dir/ to the root of the repo.

Takeaway is that option 1 is still the correct answer. WDYT?

Thanks for confirming @snehankekre, #1 seems like the answer :)
