[TC 11.55rc6] Help about CrcBlake3BlockSize does not state it is for SSD drives only

Help text:
CrcBlake3BlockSize=1024

64-bit only: Block size for Blake3 hash in MBytes. Special values:
0: 256kBytes, no memory mapping (like TC 11.51 or older)
1: 1MByte, no multi-threading
>=2: multi-threading enabled
2048: Maximum supported value (2GB)
But this change was made in release candidate 2:
HISTORY.TXT wrote: 11.05.25 Fixed: Only use multi-threading for blake3 checksums if the file is larger than 1MB and located on a local SSD. Single threaded is faster on hard drives (64)
I think the help should be adjusted because of that.

OK, I will change it to:
64-bit and on SSDs only: Block size for Blake3 hash in MBytes.
