fix(website): misc improvements

[Qjuh]

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

• Fixed api-extractor config, as it was invalid and made api-extractor always run with es3 as target
• link tags to js builtins now also link to their documentation, formerly only worked in types
• remove unneccessary | inname: | Type tokens
• fix tsdoc in mainlib index.d.ts

Status and versioning classification:

• Code changes have been tested against the Discord API, or there are no code changes
• I know how to update typings and have done so, or typings don't need updating
