Released Tar-Balls Version 3.12.1 do not include Version Update

[mvtec-lallathin]

Description
The released tar-balls of version 3.12.1 on GitHub and the official website do not include the commit which updates the versions from 3.12.0 to 3.12.1 and the update of the year in the copyrights in the license file.

Merge of the referenced commit: #1095
Used download link of the Tar-Ball (URL from LAPACK Website in section https://www.netlib.org/lapack/#_lapack_version_3_12_1 points to the same URL for downloading): https://github.com/Reference-LAPACK/lapack/archive/refs/tags/v3.12.1.tar.gz

Steps to reproduce:

1. Download tar-ball
2. Extract tar-ball using e.g. tar -xvzf lapack-3.12.1.tar.gz
3. Check versions:
   1. CMakeLists.txt LAPACK_PATCH_VERSION is still 0: set(LAPACK_PATCH_VERSION 0)
   2. INSTALL/ilaver.f VERS_PATCH is still 0: VERS_PATCH = 0
   3. LICENSE still references year 2023

Why is this important for us:
We want to use LAPACK as a thirdparty and therefore the "officially" released version including the appropriate LICENSE file.
