releasenote.md: add information about 06-ba-08 microcode file

This microcode file was first appeared as part of microcode-20240312,
was present in the following releases up to microcode-20241112,
and was removed in microcode-20250211.  While [1] mentions
that there are no products in production that would use that microcode,
it does not warrant creation of discrepancy between the release notes
and the actually shipped contents;  moreover, presence of 60BA8 CPUID
in [2] hints at its possible availability, after all.

NB: This CPUID can still be updated with the latest 06-ba-0* microcode
even despite removal of the microcode file, as it shares the microcode
data with 06-ba-02 and 06-ba-03 microcode files, that still contain
it in the extended signature:

    % iucode_tool -L microcode-20250211/intel-ucode/06-ba-02
    microcode bundle 1: microcode-20250211/intel-ucode/06-ba-02

               sig 0x000b06a2, pf_mask 0xe0, 2024-07-31, rev 0x4124
