fix(deps): bump C++ server dep for holdouts fix (#109)

This also switches to forks of the lua/luajit CI action, which have been
forked into the `luarocks` org.

The forks seem to be more up-to-date and are capable of fetching
`luajit`, which is apparently not working with the old version of the
action as LuaJIT is now distributed only via git.
