Leah Rowe b74a7f0cc6 Bump GRUB revision to add 73 security patches
You can find information about these patches here:

GRUB has been on a crusade as of late, to proactively audit
and fix many security vulnerabilities. This lbmk change brings
in a comprehensive series of patches that fix bugs ranging from
possible buffer overflows, use-after frees, null derefs and so on.

These changes are critical, so a revision release *will* be issued,
for the Libreboot 20241206 release series.

This change imports the following 73 patches which
are present on the upstream GRUB repository (commit IDs
matched to upstream):
