Miscellaneous formatting improvements to website

[aliabd]

Small formatting fixes to docs and guides.

Fixes #1717

@abidlabs can you document the visible and variant params in BlockContext? Just fill the content where I put the TODO

Looks good to me @aliabd ! Thanks for making these improvements.

Only thing is that color_map in Chatbot is still undocumented. Looks like we deprecated that parameter in favor of Chatbot.style. Maybe we just add color_map to the docstring saying it's deprecated? Not blocking merge though

Seems unnecessary to document the color_map parameter if it's deprecated I think? Let's instead make sure we document the style() methods for all of the components, as mentioned in #1757

Done @aliabd!
