simple config command just for setting default registry

[calvinrp]

Just a bare minimum config subcommand for setting the default registry.

wkg config prints current default registry
wkg config --default-registry {REGISTRY} sets the default registry
wkg config --edit launches editor ($EDITOR env var) with the config file

Can follow up with an addition PR for other config options.

I'd maybe make the flag name a little more explicit, e.g. --default-registry

Two possible follow-up features that I think would have a good bang-for-buck:

• wkg config: print the current config
  • probably need some #[serde(skip_serializing_if)] on the ConfigToml to make this digestible.
• wkg config --edit: open the global config file in $EDITOR

Thanks for the recommendations, @lann . I will update shortly.

Added wkg config --edit to launch editor.

All good to go from my side. Mostly comments/nits that don't necessarily need to be addressed before merge

Shoot - forgot to submit review. Not super critical but these comments do show up in --help.

Thanks!
