Update the TPM 2.0 Keys for Device Identity and Attestation PDF reference?

The README.md is referencing the draft at:

https://trustedcomputinggroup.org/wp-content/uploads/TCG_IWG_DevID_v1r2_02dec2020.pdf

In the mean time, the final version of that document seemed to be released at:

https://trustedcomputinggroup.org/wp-content/uploads/TPM-2p0-Keys-for-Device-Identity-and-Attestation_v1_r12_pub10082021.pdf

Which is referenced from https://trustedcomputinggroup.org/resource/tpm-2-0-keys-for-device-identity-and-attestation/

Can this repository README.md file be updated to point to the final version? Or does that has any impact on the underline implementation/code?

Start with README.md and compare the two TPM 2.0 Keys for Device Identity and Attestation URLs. Confirm whether the README reference can use the final document without affecting the implementation, then update the link if appropriate and verify the README points to the intended final version.
