change of all unique IDs in ATT&CK v15.1 commit

[cvandeplas]

We notice in commit 5938264 with ATT&CK v15.1 info, that all unique IDs of ATLAS have changed to a new ID.

For example "Search for Victim's Publicly Available Research Materials", had as ID attack-pattern--65d21e6b-7abe-4623-8f5c-88011cb362cb.
Since the new release the ID us now attack-pattern--41420aee-d3d0-413a-9528-9deb8b1fddba.

A change in IDs unfortunately breaks all references whenever ATLAS data is being used.
As you may know, MITRE ATLAS is also made available as a MISP Galaxy, and therefore available as tag and metadata to the thousands of MISP Threat Sharing communities, and any other software that uses this source of information.

Was this an intentional change, or was it accidental?
It'd be great to know as we can give it a bit of time to fix before merging the change.

Thank you again for the great work with ATLAS !
