Protobuf update commands with make not working

[deverman]

hi, the docs in the readme for rebuilding the protobuf definitions if a new Keynote is released don't seem to be working:

https://github.com/psobot/keynote-parser?tab=readme-ov-file#updates

cd dumper
make clean
make

This is what I get in my terminal:

deverman@Brents-MacBook-Pro-2 keynote-parser % cd dumper make clean make

make: *** No rule to make target `clean'. Stop. make: *** No targets specified and no makefile found. Stop. deverman@Brents-MacBook-Pro-2 dumper % pwd /Users/deverman/Documents/Code/slides/keynote-parser/dumper

please guide me if there is anything else I should be doing to get this to work.
