Bump version to 0.6.0

Preparing 0.6.0 release, which is probably a bit overdue already.
Also it's nice to align the release with PyTorch conference.

- Added `torch.utils._pytree._register_pytree_node` and `torch.backends.cuda.sdp_kernel` to the deprecated APIs rules
- Enhanced rule TOR203 to support `torchvision.datasets` and `transforms` in addition to `models`
- Added rules TOR106 and TOR107 to suggest replacing `torch.log(1 + x)` and `torch.exp(x) - 1` with more numerically stable equivalents
- Multiple code refactorings, bug fixes, and quality of life and documentation improvements
