Feature Request: Option to disable sitemap XSL stylesheet

[sbstnslg]

Hey Tobi! 👋
Thanks for this amazing plugin and i have a small feature request:

Request:
Add a config option to disable the XSL stylesheet in the sitemap:

'tobimori.seo.sitemap.stylesheet' => false, // default: true

Why:
Some users prefer the raw XML output without styling for better compatibility with SEO tools and crawlers.

Impact:
Gives users full control over sitemap presentation to search engines.

No rush at all – just wanted to share this idea. Thanks for your great work! 🙏

Some users prefer the raw XML output without styling for better compatibility with SEO tools and crawlers.

Surely this should make no difference? Crawlers don't see the XSL at all. Do you have a source for this claim?

Fair point, i checked and didnt find any real compatibility issues, but I still have a few reasons:

1. Blank page locally: When I open the sitemap locally, it shows a blank page. The SEO Framework docs say this can happen because of XSL (CORS-related), and turning it off fixes it.

2. Personal preference: I just like seeing the raw XML for quick checks.

3. Common pattern: Other SEO tools include this option, so maybe theres user demand.

Totally fine if its not worth adding, appreciate you taking a look 🙏
