have you thought about instead making a type glossary? can do this per package: https://viem.sh/docs/glossary/types.html

right now, these might be too much info around types. additionally, this sets a precedent that we should include docs on each type, which I think bloats our documentation a bit too much for my liking.

most of these types X have an "ifX()" method. Maybe we document those instead?

@avasisht23 @moldy530 I have put the basic types to the glossary section. I kept the user operation provider specific types to Provider/Types section. Following the pattern of what's done on viem doc.
