Video Sitemap: description should filter out HTML tags

[htdat]

Steps to reproduce the issue

1. Upload a new video to Media Libary
2. Add the description of the video, which includes HTML tags like <p>something</p>.
3. Check the sitemap.

What I expected

Just something without the HTML tags.

What happened instead

It displays exactly like <p>something</p>

I tracked down the related code:

jetpack/modules/sitemaps/sitemap-builder.php

Lines 1317 to 1321 in 6cf62b5

	/** This filter is already documented in core/wp-includes/post-template.php */
	$content = apply_filters( 'the_content', $content );
	/** This filter is already documented in core/wp-includes/feed.php */
	$content = apply_filters( 'the_content_feed', $content, 'rss2' );

A possible solution is to add another filter:

$content = wp_strip_all_tags ( $content, true );

I will test again and propose a PR.
