[js-api] Fix some editorial issues. (WebAssembly#858)

* Add a missing closing curly brace.

* Fix link to the definition of the Global constructor.

* Replace an unreachable step by an assertion.

* Fix the link to Table::grow().

This also required distinguishing the two grow() methods.

* Link the Module static methods to their definition.

* Make the assertion in ToWebAssemblyValue part of the algorithm.

* Make the assertion in ToJSValue part of the algorithm.

* Remove stray period in the note about ToJSValue.

* Change `6.` to `1.`
