* Use DesiredPropertiesError instead of strings
Using an object allows typescript to error in more cases as with strings
if the original propriety was a string it would not error for stuff like
`.endsWith(...)`
We use a symbol to make sure the type doesn't actually become a generic
object, but instead is a specific type that can be checked against.
* Update docs
* Remove TBot, Use SetupDesiredProps
* Remove even more clutter from intellisense
* Use type instead of interfaces for some types
This avoids the need for mapped types in Bot
* docs: add info about removing ts clutter to desired props guide
* docs: improve ts clutter section in desired props guide more
