read_delim() called with unused data.table argument

[ariannalandini]

When providing sdY through a file, the pipeline fails due to an invalid argument being passed to read_delim(). The data.table = F parameter appears to be a possible leftover from a previous implementation using fread().

In s02_sumstat_munging_and_aligning.R, read_delim() is called with data.table = F. The readr::read_delim() function does not support this argument, causing the following error:

Error in read_delim(sdY, data.table = F) :
  unused argument (data.table = F)

The data.table = F argument should be removed.
