Support for Typescript 4.x
Describe the feature
I am told that the reason that AWS CDK depends on Typescript 3.9 is beacuse of jsii in #18743, I am now stuck in a situation where cdk cannot use typescript above 3.9 and tsc cannot use typescript below 4.2 (due to @types issue 60310). While that might get reverted eventually, it points to the long term unsustainable nature of requiring a version of a key library that is both an entire major version behind and 7 overall releases behind.
Use Case
Compatibility: I cannot run cdk after running npm up at all because @types/prettier automatically upgrades unless manually pinned (which I did not know to do), nor can I initialize a new cdk workspace with typescript because the install grabs the latest version of @types/prettier which won't work with the required version of typescript.
Proposed Solution
Upgrade the supported version of typescript.

CDK version used
2.28.1 (build d035432)
Environment details (OS name and version, etc.)
Ubuntu 20 LTS with node 16 from https://nodesource.com/, but also tested and verified on OSX 12.2 with node from homebrew
There was an attempt with https://github.com/aws/jsii/pull/1940 but it never was merged due to potential breaking changes.
I really hope it would be done anyway at some time as this is making things tricky very often, and the situation won't improve
There's a proposal out with https://github.com/aws/aws-cdk-rfcs/pull/373 to fix this, but I'm not sure what it's present status is.
@RichiCoder1 you're correct, this is the current plan. I've investigated doing a "bring your own typescript" with adapters but it turns out to be nearly impossible to do without creating a maintenance nightmare.
The RFC still stands as the best plan I have so far, and I would like to implement that sooner rather than later (but so far received very little traction/interest).
