[Bug?]: TypeScript 6+ is not correctly patched / does not work properly with PnP

Self-service

• I'd be willing to implement a fix

Describe the bug

TypeScript 6+ is not being correctly patched; typescript is failing to correctly resolve PnP types packages (@types/*, e.g. @types/node).

To reproduce

@hamidrezahanafi - I'm going to be pedantic here.

This is not a dupe; that issue covers install and TS7, this covers TS6 which installs fine (and will build your project) - it just doesn't typecheck correctly for PnP workspaces.

TS7 may or may not be able to be patched - with TS7 being a go port of the TS compiler I am not sure how a patch would even work.

TS6 is remains TypeScript/JavaScript and is, likely, quite patchable.

The duplication that does exist is the overzealous patch version range causing an inadequate patch to apply.
