Update typescript, ttypescript, typedoc

[cliffoo]

Second attempt! I overlooked typedoc warnings the first time so that was reverted.

Update typescript to latest 4.x (4.9.5), ttypescript to latest (1.5.15), typedoc to latest (0.24.8).

if it builds it builds I guess!

Well, unless it builds with serious documentation warnings. Currently checking that...

OK, there are indeed no nasty documentation warnings, hooray!

There are some deprecation warnings emitted by ttsc. I don't know how bad these are. Can anyone (@gnidan?) weigh in?

Specifically, they are:

@truffle/codec: DeprecationWarning: 'updateImportDeclaration' has been deprecated since v4.8.0. Decorators are no longer supported for this function. Callers should switch to an overload that does not accept a 'decorators' parameter.
@truffle/db: DeprecationWarning: 'updateImportDeclaration' has been deprecated since v4.8.0. Decorators are no longer supported for this function. Callers should switch to an overload that does not accept a 'decorators' parameter.
@truffle/db: DeprecationWarning: 'updateImportTypeNode' has been deprecated since v4.6.0. Use the overload that accepts 'assertions'
@truffle/db: DeprecationWarning: 'updateExportDeclaration' has been deprecated since v4.8.0. Decorators are no longer supported for this function. Callers should switch to an overload that does not accept a 'decorators' parameter.
@truffle/db-kit: DeprecationWarning: 'updateImportDeclaration' has been deprecated since v4.8.0. Decorators are no longer supported for this function. Callers should switch to an overload that does not accept a 'decorators' parameter.

...my guess though is that since the tests all pass, these can't be too serious. So what the hell, I'll approve it too.
