Twenty Nineteen: Fix inconsistent HTML comments after closing HTML tags.

[iamdmitrymayorov]

Some comments after HTML closing tags are either incorrect or inconsistent. I first discovered one in header.php.

Should be:

<div class="site-branding-container">
        <?php get_template_part( 'template-parts/header/site', 'branding' ); ?>
</div><!-- .site-branding-container -->

Was:

<div class="site-branding-container">
        <?php get_template_part( 'template-parts/header/site', 'branding' ); ?>
</div><!-- .layout-wrap -->

After that I checked comments after closing HTML tags in all theme files and found another incorrect one in template-parts/header/entry-header.php. Should be <!-- .entry-meta --> but was <!-- .meta-info -->.

Lastly, some comments that are placed right after the tags that have dynamic IDs were inconsistent. I've found three versions <!-- #post-## -->, <!-- #post-${ID} -->, and <!-- #post-<?php the_ID(); ?> -->. The last one actually prints the ID in HTML. I have updated all occurrences to use <!-- #post-<?php the_ID(); ?> --> for consistency.

Fixes the same issue in other default themes.
