update to go1.23.6

This minor release include 1 security fix following the security policy:

- crypto/elliptic: timing sidechannel for P-256 on ppc64le

  Due to the usage of a variable time instruction in the assembly implementation
  of an internal function, a small number of bits of secret scalars are leaked on
  the ppc64le architecture. Due to the way this function is used, we do not
  believe this leakage is enough to allow recovery of the private key when P-256
  is used in any well known protocols.

This is CVE-2025-22866 and Go issue https://go.dev/issue/71383.
