Fix dev docs

[Timothy-Gonzalez]

Updates typedoc & plugin to latest, disables external dependency documenting. We really shouldn't be doing this anyways, as depending on other people's code to be commented in the right format is very iffy.

Summary about this issue if we want to fix it

• Originally, typedoc updated to ts 5.2, which is why we has issues using new ts with old typedoc: ts 5.2 API Change: labeledElementDeclarations can contain undefined TypeStrong/typedoc#2369
• So, upgrading typescript & typedoc, we had a new issue: recursive commenting until call stack is reached:

[info] The comments for _id are declared at:
        ./node_modules/mongoose/types/document.d.ts:22
        ./node_modules/mongoose/types/document.d.ts:22
        ./node_modules/mongoose/types/document.d.ts:22
        ./node_modules/mongoose/types/document.d.ts:22
TypeDoc exiting with unexpected error:
RangeError: Maximum call stack size exceeded
    at get project [as project] (....\hackillinois\adonix\node_modules\typedoc\dist\lib\models\reflections\abstract.js:251:24)
    at get project [as project] (....\hackillinois\adonix\node_modules\typedoc\dist\lib\models\reflections\abstract.js:255:36)
    at get project [as project] (....\hackillinois\adonix\node_modules\typedoc\dist\lib\models\reflections\abstract.js:255:36)

• This matches a issue from a few months ago: Maximum call stack size exceeded if there is a prop with type React.ReactNode TypeStrong/typedoc#2145
• We can't fix this - so this is the best solution. For reference, this is the line in mongoose that causes this issue for SOME reason: https://github.com/Automattic/mongoose/blob/0945da57539e43d99d0600fcc3ce7e581ad1f21d/types/document.d.ts#L23
