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 @videoUrl https://www.youtube.com/embed/maI2u6Sxk9M @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 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.
