When site uses Yoast SEO, the rewrite rule is conflicting and the one added by Yoast SEO takes precedence, causing 404 for /news-sitemap.xml

[pushpakpop]

Describe the bug

Yoast SEO is adding rewrite rules by filtering the rewrite rules array using the filter option_rewrite_rules rather than using the add_rewrite_rule rule functionality and adds its sitemaps related rewrite rules at the top of the array.

As a result, the below rewrite rule added by Yoast SEO takes precedence :
[([^/]+?)-sitemap([0-9]+)?.xml$] => index.php?sitemap=$matches[1]&sitemap_n=$matches[2]

The rewrite rule that this plugin adds is [^news-sitemap.xml$] => index.php?news-sitemap=true.

As the regex "([^/]+?)-sitemap([0-9]+)?.xml$" catches the news-sitemap.xml, it is going to 404 page

This can be resolved by having the sitemap_slug to be different such that it is not caught by Yoast's rewrite rule regex "([^/]+?)-sitemap([0-9]+)?.xml$"

May be even allowing a filter to change the sitemap slug could work?

For now, the only option to make this working is to use the filter "option_rewrite_rules" and manually place the '^news-sitemap.xml$' related rule to the top of the array, making it take precedence over the Yoast SEO's rules.

Steps to Reproduce

1. Have a website with Yoast SEO plugin Installed and activated
2. Install this plugin
3. Flush Permalinks
4. Try visit your-site.com/news-sitemap.xml
5. It shows 404.
