Docs: Add note about enqueueing assets in the iframe and trim whitespace.

[ndiego]

What?

Updates the Enqueueing assets in the Editor doc based on @ellatrix's feedback. While updating the doc, I also trimmed all extra whitespace.

Edit: in preparing this PR, a number of typos were also found and fixed.

Conflicts. 😞 Happy to review once resolved.

@ndiego In the wp_enqueue_script and wp_enqueue_style function calls, they are terminated via ); but there is an existing } on the following line. I believe this will cause a syntax error when executing this function. The closing } for the function should be at the same indent level hints the last } before the add_action hook. The others should likely be removed.

@ndiego There is still a problem with this first code snippet.

/**
 * Enqueue Editor assets.
 */
function example_enqueue_editor_assets() {
    wp_enqueue_script(
        'example-editor-scripts',
        plugins_url( 'editor-scripts.js', __FILE__ ) );
    }
    wp_enqueue_style(
        'example-editor-styles',
        plugins_url( 'editor-styles.css', __FILE__ ) );
    }
}
add_action( 'enqueue_block_editor_assets, 'example_enqueue_editor_assets' );

Rewrite to:

/**
 * Enqueue Editor assets.
 */
function example_enqueue_editor_assets() {
    wp_enqueue_script(
        'example-editor-scripts',
        plugins_url( 'editor-scripts.js', __FILE__ )
    );
    wp_enqueue_style(
        'example-editor-styles',
        plugins_url( 'editor-styles.css', __FILE__ )
    );
}
add_action( 'enqueue_block_editor_assets, 'example_enqueue_editor_assets' );

Thanks @alexstine, and there was a missing ' in the add_action. All fixed. I also updated the description of this PR to reflect these changes 😅
