feat(website): type parameters links, builtin doc links, default values

[Qjuh]

Please describe the changes this PR makes and why it should be merged:

• TypeParameters of class, interface, type alias or function used in one of their members now link to the type parameter declaration on their parent
• moved the generation of builtinDocumentationLinks from the website to the generateSplitDocumentation script. needs to stay in website too for now to support loading already existing api.json files that don't have the links in them yet
• default values show in the excerpt for parameters of methods/functions as well as properties of interfaces

Also fixed two minor doc related nits in discord.js.

Status and versioning classification:

• I know how to update typings and have done so, or typings don't need updating
• This PR only includes non-code changes, like changes to documentation, README, etc.
