Add a config method (or something like that) that allows you to edit the config interactively

[mattstauffer]

Running lambo edit-config --interactive presents the user with a series of interactive questions that guide them through setting the various default options that will be saved in their ~/.lambo/config file.

$ lambo edit-config --interactive

Please specify a location where new Laravel projects should be created:
/some/path

Please choose a default editor: [vim]
[1] vim (current shell default)
[2] nano
[3] vscode
[4] Sublime Text
[5] Specify something else
1
⋮

You set the following defaults, please review them. 
You can enter 15 to save them or chose a corresponding number to edit that option.

[1] default project location: /some/path
[2] Prefered editor: vim
⋮
[15] This looks good, save them as my defaults.
