vue ui generate project package.json with correct name property.

What problem does this feature solve?

Recently, I generated a project in the "Vue-CLI-3-test" folder, everything went fine, but the "name": "Vue-CLI-3-test" property seems to be wrong.

I get this warning from my IDE: "String is violating the pattern: ^(?:@[a-z0-9-~][a-z0-9-._~]*/)?[a-z0-9-~][a-z0-9-._~]*$ (This inspection checks that JSON files conform to JSON Schemas assigned to them).

What does the proposed API look like?

Simply turn the words into lower case: "name": "vue-cli-3-test". This helped me correct the warning.

I'd love to work on this, looks like a good first issue :)
