Clarify that code type 0xC4 uses a 64-bit value in cheats.md by formatting the key values as such ...

Changes the formatting of the key values at `Code Type 0xC4: Begin Extended Keypress Conditional Block` in cheats.md so that it is perfectly clear that those values are 64-bit values rather than 32-bit or 28-bit like `Code Type 0x8: Begin Keypress Conditional Block`, and also for the fact that the formatting matches the rest of the document and is thus cleaner.
