Commit e6169f17f9 switched from searching `Data/` to searching
`data/`. For users on case-insensitive filesystems, this is a no-op and
the instructions that reference the `Data` directory continue to work.
For users on case-sensitive filesystems, the change broke accessing the
data directory, and caused the instructions to mislead. Given the age
of the commit, fixing the capitalization now will likely cause more
problems than it solves. Instead, fix the capitalization of the
instructions, so that users who follow the documentation get a working
setup.
