chore: remove unused config file
chore: remove unused config file

Some more cleanup following on from df1471519a6bfef1 ("chore: remove
vendor/vimscriptuploader", Jul 24 2022), which said:

> Last reference removed in 9c7f81208a32fe4d ("chore: battle bit-rot in
> gem dependency graph", May 9 2020). I've been manually uploading
> releases since then.

This config file was added all the way back in b47221fb41922260
("Rakefile: tweaks to get vimscriptuploader.rb working", Mar 26 2011)
and was never touched again, until now.
