feat(pacmak): allow typeguard==3.x and typeguard==4.x (#4611)

Currently python projects generated by pacmak define a `typeguard` dependency range of  `typeguard~=2.13.3`, which prevents users from brining newer major version of `typeguard` into their projects. 

This PR adds support for `typeguard==3.x` and `typguard==4.x`, which are the latest versions currently available. We intentionally do not allow an open range because every major version brings breaking changes with it that might need to be addressed.

### Notes

- We couldn't just drop support for `typeguard==2.x` because that would be a breaking change. 
- We could potentially release a new major version of pacmak to make the code more maintainable. My take is that this PR doesn't complicate the code to the extent of justifying a new major version, but lets discuss.

Fixes #4469
