Autocomplete

[beeinger]

Hey, been using cargo make and it's great, however I very much missed some autocomplete.
I realise it's not a subject for a PR to this repository, however I wanted to share this for anyone looking.

I'm currently using Fig, so I made this PR, will update you here if it gets merged.

When it gets merged you will be able to use Fig and get autocompletion on all available flags.
Most importantly it autocompleted the custom tasks commands from the Makefile.toml.
Resolving different locations of the makefile also works when the --makefile <file> flag is provided.

If anyone is interested in improving this lmk, also if there are any updates to the cargo-make API in the future, an update to Fig will be needed.

thanks! that's great

1. i do have in this repo auto complete solutions such as bash and readme points to that
2. when your PR is keeged, can you do a PR for cargo make to document that?

Sure! I didn't notice the Shell Completion chapter 👀
It's merged already so will make a PR here now.
