feat: commit the corrected file of each platform

exports/ now holds the twelve platforms' own files, corrected, with a
report of every change, read by the site's corrected files page. Two
summaries are reworded for the page: an addition the format cannot
carry is counted as left out, and RetroPie names each skipped package
by sentence instead of joining reasons with semicolons. Its parser no
longer reads "e.g" as a file name.
