Aliases to recipes in submodules

[john-cd]

To "alias" a recipe in a module, I believe one has to call just again:

# Format all bin and lib files
f:
  @just code fmt

# Format all packages and their local path-based dependencies
fa:
  @just code fmtall

Could we have the following?

alias f  := code::fmt

Good suggestion! I added it to #2252.

I think this should be pretty easy to add, so added the good first issue label in case anyone wants to take a crack at it.
