[Docs] - Error in Syntax of JavaScript in web/README.md

[mrosata]

There is a close parenthesis ) after the closing curly brace } on the if statement.

firebase.auth().onAuthStateChanged(function(user) {
  if (user) {
    firebase.authMigrator().clearLegacyAuth();
  });
});

should be:

firebase.auth().onAuthStateChanged(function(user) {
  if (user) {
    firebase.authMigrator().clearLegacyAuth();
  };
});
