pldmtool: correct help text for GetPLDMCommands

The previous help example showed the PLDM version bytes in the wrong
order, leading to incorrect requests. The version bytes must be
specified as [alpha update minor major] to match the ver32_t decode
logic and PLDM spec (DSP4014). Updated the help text example to show
the correct order: e.g., version 1.1.0 should be `0x00 0xF0 0xF1 0xF1`.

This helps users avoid confusion when passing version data to --data.
