Let automatically set name in package.json based on name of folder.

[Mlocik97]

Describe the problem

When I use npm init -y it automatically set name in package.json to same as name of folder. It would be nice to have same thing with npm init svelte@next.

Describe the proposed solution

Let say I'm in folder foo.

if I use command npm init svelte@next or resp. npm init svelte@next ., it should automatically set name to foo.
if I use command npm init svelte@next bar, it should automatically set name to bar,

it should also convert all capitals letter and remove invalid characters (or throw error like npm init -y), that doesn't use pattern:

"^(?:@[a-z0-9-*~][a-z0-9-*._~]*/)?[a-z0-9-~][a-z0-9-._~]*$"
