title: vscode package.json String does not match the pattern
body: <p>I am trying out VSCode on an existing project that uses npm and has a package.json file with a corresponding "name:" key that reads "SpecPro-File-Management-UI". VSCode is objecting to this line with "String does not match the pattern ...", apparently because of the upper-case characters in the name.</p>
  
  <p>This problem is described in a <a href="https://github.com/Microsoft/vscode-react-native/issues/151" rel="noreferrer">VSCode issue</a> which is closed.  Which leaves me with <a href="https://code.visualstudio.com/Docs/languages/json#_json-schemas-settings" rel="noreferrer">advice to setup a custom schema</a> for my package.json file.  This is pretty unfriendly, and a barrier to adopting VSCode.  I don't want to spend my time on custom schemas. I don't want to rename my project. I just want to edit my code and take advantage of the many VSCode goodies without distracting messages that are wrong.</p>
  
  <p><s>Considering that using uppercase characters for npm packages is a VERY common practice, </s>it seems most reasonable that VSCode should adopt either a more friendly schema or an easy way to override the standard schema. As far as I can tell, I have to make my own personal schema to resolve this problem. That's a lot of work and future maintenance for such a simple issue.</p>
  
  <p>Is there an easy way to banish this erroneous error message?</p>
