Typo in randomness concept

Hi there!

There are typos in instruction.md and about.md: psuedorandom instead of pseudorandom. I’m happy to submit a PR to fix this.

In the about.md for the randomness concept, “psuedorandom” shows up on Lines 34 & 35. javascript/concepts/randomness/about.md at 03ff634194b31d80f8a4c8b24ec555edfe69a31b · exercism/javascript · GitHub

In the introduction for the randomness concept, it appears on Lines 22 & 23.

          Generating truly random values with a computer is a [surprisingly difficult technical challenge][why-randomness-is-hard], which is why there are also "pseudorandom" generators.

          The `Math.random()` function should NOT be used for security and cryptographic applications!

          ## Generating random numbers
          
          In Javascript, you can generate psuedorandom numbers using the [`Math.random()`][Math.random] function.
          It will return a psuedorandom floating-point number between 0 (inclusive), and 1 (exclusive).
          
          To get a random number between _min_ (inclusive) and _max_ (exclusive) you can use a function something like this:
          
          ```javascript
          function getRandomInRange(min, max) {
            return min + Math.random() * (max - min);
          }
          getRandomInRange(4, 10);
          // => 5.72

In the design.md for Captain’s Log, It shows up on Line 5 but this isn’t student-facing in the same way the other docs are.

          # Design
          
          ## Goal
          
          The goal of this exercise is to teach the student how to generate psuedorandom numbers in JavaScript.
          
          ## Learning objectives
          
          - Know how to generate a random number with `Math.random()`
          - Know how to generate a random number in a range.
          - Know how to generate a random integer.
          
          ## Out of scope
          
          - Details of pseudorandom number generation in general.

in the introduction for Captain’s Log, it also shows up on Lines 22 & 23.

I don’t see any other incidents of " psuedo" in the JavaScript track docs.
