change jsx requires to require extension-less version

jsx-require-codeshift.js

/**
 * jsx-require-codeshift changes all import/require calls for .jsx files to their root files
 * 
 * this is not a very complicated jscodeshift transform, but the more the merrier imo, since there
 * aren't very many out there to peek at. (it could probably be satisfied with a not-crazy regex).
 * 
 * What this does is converts calls like `import Foo from 'foo.jsx';` to `import Foo from 'foo';`
 * and similarly, it also converts require calls for jsx files to their extensionless versions.
 *
