Chore(docs): Add composable structure section and component descriptions to documentation

Describe the issue. What is the expected and unexpected behavior?
Consider adding a "General intended structure" section to documentation for more compassable components, and add descriptions for sub-components in the "Props" section to provide more details on their use-cases.

For sub-component descriptions, we should consider ensuring that any sub-components used in examples/exported for consumer use are added to the "Props" section. For example, Application Launcher has examples using ApplicationLauncherSeparator, but that is not included in the props section of the component page. Note: this will cause an issue for sub-components that do not export a props interface, as an empty table will be rendered to that section of the component page.

Additionally, we should align on when to include other components on a page's "Props" section. The Login Page component, for example, uses List and ListItem in some examples, but does not include the props table for them. The Alert Group component on the other hand includes the Alert props table.

e.g.
General intended structure
File upload - multiple is designed in a composable manner to maximize flexibility. The general intended component relationships are arranged similarly to:

See #7603 for working examples

Needs only sub-component descriptions:

• #7973

• #7978

• #8105

• Wizard

Needs both "composable structure" and sub-component descriptions:

• Accordion

• Action list

• Alert group (currently the alert group page includes Alert specific components in the "Props" section)

• Application launcher (partially composable)

• Breadcrumb

• Card

• Clipboard copy (currently the component page includes ClipboardCopyButton in the "Props" section, but the component isn't used in any examples. If we want to keep this, it may be worth considering whether any other sub-components should be exposed on all components)

• Chip group (currently the chip group page includes the Chip component in the "Props" section)

• Code block

• Context selector

• Data list

• Description list

• Drag and drop (wait for Nicole to provide feedback)

• Drawer

• Dropdown (partially composable)

• #7692

• Empty state

• Form

• Form select

• Helper text

• Hint

• Input group

• Jump links

• Label group (currently the label group page includes the Label component in its "Props" section)

• List

• Login page

• Masthead

• Menu

• #7691

• Navigation

• Notification drawer

• Options menu (partially composable)

• Overflow menu

• Page

• Panel

• Progress stepper

• Select (partially composable)

• Sidebar

• Simple list

• Table Composable (because of the different variants of a table, the structure section may need to be split up to several different ones)

• Table Legacy (could arguably only require sub-component descriptions, but since examples show the TableHeader inside of Table it might be good to include some sort of "intended structure" section/mention)

• Tabs

• Text

• Text input group

• Toggle group

• Toolbar

Jira Issue: PF-187

从 issue 中列出的组件文档页面开始，检查示例、现有的 Props 部分以及 #7603 中可运行的示例。确定哪些子组件应归入 Props，以及哪些页面需要一个关于预期结构的通用部分，然后更新未勾选的组件页面，并确认示例和描述的文档记录保持一致。
