Generate completions at runtime #392
Description
Currently we generate completions through a separate xtask crate. Now that we use subcommands in our CLI it would be reasonable to move completion generation to a hard runtime dependency that way anyone who has an inlyne binary can generate the appropriate completions files
I'm not sure if there is a standard command name to use or whatnot, but that change should allow us to entirely remove the usage of a separate xtask crate
