Updates the docs refer to 'govuk' namespace

As part of namespacing, we need to update the links the docs point to
so that they are still valid and do not break. We also needed to update
the examples to show how to use the new namespace.

 We aim to write the description of our tests in as "natural language" as possible, for instance "back-link component fails to render if the required fields are not included".
 
 ### Running individual tests
 You can run a subset of the test suite that only tests components by running:
 
-    `npm test -- src/components/button`
+    `npm test -- src/govuk/components/button`
 
 Note: There's a watch mode that keeps a testing session open waiting for changes that can be used with:
 
-    `npm test -- --watch src/components/button`
+    `npm test -- --watch src/govuk/components/button`
 
 ### Updating component snapshots
 [Snapshot tests](https://facebook.github.io/jest/docs/en/snapshot-testing.html) are used for preventing unintended changes - when the snapshot test runs, it  compares the previously captured snapshot to the current markup. For components, the snapshots are stored in `[component-name directory]/_snapshots_`.
 
 If a snapshot test fails, review the difference in the console. If the change is the correct change to make, run:
 
-`npm test -- -u src/components/button`
+`npm test -- -u src/govuk/components/button`
 
 This will update the snapshot file. Commit this file separately with a commit message that explains you're updating the snapshot file and an explanation of what caused the change.
