Storybook: Restore ability to boot stories only from packages/components

[jsnmoon]

Related to #76007.

Proposed Changes

• Updates repository storybook configuration to include JS & JSX stories from the components package.
• Updates story titles for JS/JSX stories from the components package.
• Restores standalone storybook functionality for @automattic/components.

My reason for restoring the components package's storybook functionality is simple: It boots much more quickly than the repository-wide storybook. @Automattic/red frequently works on components within @automattic/components and would benefit from this quicker boot time. See these two screenshots:

Repository-wide	Components Package
215s to boot	15.7s to boot

Testing Instructions

Repository-wide Storybook

• Boot the repo-wide storybook via yarn storybook:start.
• Ensure that all stories, including previously excluded ones like the "Component swapper", work as expected.

Components Package Storybook

• Boot the components package storybook via yarn workspace @automattic/components run start-storybook
• Ensure that all stories for the components package work as expected.

I had mentioned in the description of #75676 about the start-up time.
This could be better with the incremental build. https://storybook.js.org/blog/storybook-on-demand-architecture/ CC: @Automattic/team-calypso
