package/mmc-utils: fix hash mismatch for readme file
Commit b03dc5: package/mmc-utils: bump to 523d8f3cfb21
The README hash changed causing a build failure:
https://github.com/skiffos/SkiffOS/actions/runs/12266361526/job/34224344838#step:8:60617
Update the hash for the README.md file to fix the issue.
