Update wasm-pack tutorial paths

[mgattozzi]

We're just waiting for a 0.2 release of wasm-pack right now for this issue. In https://github.com/rust-lang-nursery/rust-wasm/pull/151 we changed a path reference from ./node_modules/@MYSCOPE/wasm-add/wasm_add.js to @MYSCOPE/wasm-add/wasm_add.js. As was noted in #151 after https://github.com/ashleygwilliams/wasm-pack/issues/94 is closed we can shorten this further to @MYSCOPE/wasm-add which is more idiomatic for JS.

Mentoring instructions:

1. In src/wasm-pack/run-the-code.md change the import statement of index.js to the above statement.
2. Test that the changes work as part of the tutorial with the new syntax

Hey, @mgattozzi I have gone through ashleygwilliams/wasm-pack and found that 0.2 was released. I suggest that we remove the blocked label. 😃

Hey @adityac8 thanks for reminding me. This should be good to go now :D
