Adds categories to Storybooks navigation

[mattrwalker]

What?

This pull request includes several changes to update the titles and IDs of various components in the Storybook configuration files to better reflect their categories. The most important changes involve updating the titles to group components under more specific categories and adding unique IDs for each component.

Updates to component titles and IDs:

• packages/components/src/button/stories/index.story.tsx: Updated the title to Components/Actions/Button and added an ID components-button.
• packages/components/src/card/stories/index.story.tsx: Updated the title to Components/Containers/Card and added an ID components-card.
• packages/components/src/navigable-container/stories/navigable-menu.story.tsx: Updated the title to Components/Containers/NavigableMenu and added an ID components-navigablemenu.
• packages/components/src/navigable-container/stories/tabbable-container.story.tsx: Updated the title to Components/Containers/TabbableContainer and added an ID components-tabbablecontainer.
• packages/components/src/panel/stories/index.story.tsx: Updated the title to Components/Containers/Panel and added an ID components-panel.

This creates an 'Actions' category and a 'Containers' category within the left-hand navigation.
This change represents 2 out of the 12 categories to be introduced, it's smaller scope allows me to test run committing before making larger changes at a later date and time.

Why?

This change is part of the larger Storybook Improvements and the shared Sitemap.

How?

Adding Categories that helps organize and group components into sections based on their role and function within the library makes our library easier to navigate and understand.
