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 Missing Token @category compiler @shortDescription No suitable injection token for parameter

@description There is no injection token for a constructor parameter at compile time. InjectionTokens are tokens that can be used in a Dependency Injection Provider.

@debugging Look at the parameter that throws the error and all uses of the class. This error is commonly thrown when a constructor defines parameters with primitive types like string, number, boolean, and Object.

Use the @Injectable method or @Inject decorator from @angular/core to ensure that the type you are injecting is reified has a runtime representation. Make sure to add a provider to this decorator so that you do not throw NG0201: No Provider Found.
