message: Update this script so that it works on Linux.
  Make `fd` the default name of the program, but allow for the user to specify another, such as `FD=fdfind scripts/update-version.sh`.
  Fix the sed command to take the filename to modify in-place and specify that the regex string is the sed-expression to execute.
