BUG - Sev-3 - Web - Fix custom docs template

[narin]

What happened?

We were previously using a custom docs template for Storybook to prepend a link to the documentation site. Upgrading to Storybook 7 broke this somewhat, because code snippets no longer worked when using a custom template. This might be fixable, but it might also be a Storybook bug.

Steps to Reproduce

1. Re-add the following docs parameter to one of the component stories. e.g.

   parameters: {
   docs: generateDocs({
     name: 'Button',
     docUrl:
       'https://department-of-veterans-affairs.github.io/va-mobile-app/design/Components/Buttons%20and%20links/Button',
   }),
   },

2. Load up storybook on web
3. Go to the Docs page for the modified story
4. Notice that "Show code" is disabled and says "No code available"

Desired behavior

We should be able to use a custom docs template with auto-generated code snippets

Acceptance Criteria

• [ ] Fix the generateDocs util to display the auto-generated docs link
• [ ] Code snippets should work
• [ ] If unable to fix, create a bug on the storybook repo
