Joe Martin (Crowdstaffing) 42289f25c6 docs: improve markdown (#45325)
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,
```

@name Pipe Not Found
@category runtime

@shortDescription Pipe not found!
@description
Angular can't find a pipe with this name.
The pipe referenced in the template has not been named or declared properly.
A [pipe](guide/pipes) must be either declared or imported in the `NgModule` where it is used, and the name used in a template must match the name defined in the pipe decorator.
@debugging
Use the pipe name to trace the templates or modules where this pipe is declared and used.
To resolve this error, ensure that:
* A local custom pipe is uniquely named in the pipe's decorator, and declared in the `NgModule`, or
* A pipe from another `NgModule` is added to the imports of the `NgModule` where it is used
If you recently added an import or declaration, you may need to restart your server to see these changes.
