Example error in “beegfs-ctl --hashdir --help”

[hegongshan]

Describe the bug
When I try to execute the command "beegfs-ctl --hashdir --help", I noticed that the example in the help section is incomplete. The --hashdir mode is missing.

Relevant Codes: https://github.com/ThinkParQ/beegfs/blob/master/ctl/source/modes/ModeHashDir.cpp#L101

/**
 * Just print the help
 */
void ModeHashDir::printHelp()
{
   // omit some codes
   std::cout << "  $ beegfs-ctl --type=inode 4C08-51FBAC63-7C" << std::endl;
}

Describe the system
BeeGFS 7.4.5

To Reproduce

$ beegfs-ctl --hashdir --help
# omit some output

 Example: Print an inode path
  $ beegfs-ctl --type=inode 4C08-51FBAC63-7C

In the above example, the --hashdir mode is missing.

Expected behavior

$ beegfs-ctl --hashdir --help
# omit some output

 Example: Print an inode path
  $ beegfs-ctl --hashdir --type=inode 4C08-51FBAC63-7C
