Phase 2 sample code conversions per instructions in doc: https://docs.google.com/document/d/1QqnVK8Mc0O1gU9ctPrs-JJ42V9_dHCuEttD_01pXh34/edit
**Included**
1. ajs-quick-reference
Minor changes to remove references to NgModule. Converted sample to standalone.
2. architecture
Migrated the code sample. Made minor changes to remove references to NgModule. I explicitly deprecated the `architecture-module.md` page and removed it from the navigation.
4. deprecations / deprecations-guide
Migrated the code sample which required pulling NgModule and Reactive Forms material into a new `deprecated` folder. Made minor changes to clarify when advice was specific to NgModule (see `loadChildren` in particular).
5. displaying-data
Deleted this `displaying-data` sample entirely as there is no need for a sample app just to display a single, vanilla data binding in the deprecated `zone.md` page. Replaced reference in `zone.md` with an inline code snippet.
10. ngcontainer
Converted the code sample. There is no guide page for this sample. It can be displayed in Stackblitz
**Excluded**
3. cli-builder
Code sample is not an app; nothing to convert.
6-9 - related to getting-started and setup.
Waiting until Angular team is ready to proceed.
11. providers
This is in its own commit and PR 51918 because it may not make sense to convert. See that PR for details.
12. routing-with-urlmatcher
No work needed. Already Standalone.
13 schematics-for-libraries
Non-trivial (see doc notes) and Angular may decide to leave as is. Should have own PR.
14 setup
Non-trivial (see doc notes) and Angular may decide to leave as is. Should have own PR.

The purpose of the changes is to clean all markdown to match a single pedantic style.
* To ensure all changes in style are properly separated.
* To ensure all styled content aligns to nearest 4-character-tab.
* To ensure all code blocks use the Angular `<code-example>` or `<code-tab>` elements.
* To ensure all markdown exists outside of html tags.
* To ensure all images use the Angular style for `<img>` elements.
* To ensure that all smart punctuation is replaced or removed.
```text
’, ’, “, ”, –, —, …
```
* To ensure all content does not conflict with the following reserved characters.
```text
@, $, *, &, #, |, <, >,
```
* To ensure all content displays using html entities.
The following changes were made to files in the following directory.
```text
aio/content
```
The target files were markdown files.
The list of excluded files:
```text
.browserslistrc, .css, .conf, .editorconfig, .gitignore, .html, .js, .json, .sh, .svg, .ts, .txt, .xlf,
```

Reference #33259
Removes figures elements as AIO is not typically using captions or image groups where figures would be necessary or appropriate
PR Close#33748
PR#28396 originally addressed an update via issue #23983 to make images more visible with a white background (implementation of gray "lightbox").
This PR implements those styles defined in PR#28396.
