Describe the Bug

Starting with astrojs/sitemap 1.3.0, endpoints like rss.xml are included in sitemap-0.xml.
Should sitemap include endpoints (data, images, rss etc.) at all?

If so, the trailing slash needs to be trimmed as the URLs are invalid.
<url><loc>https://example.com/rss.xml/</loc></url>

Repro: Run build in stackblitz sample and inspect sitemap-0.xml

Bonus: it doesn't add dynamic endpoints, only static. Still in 1.3.3
Ex.

• rss.xml.ts -> included as rss.xml. Ok, but should users really have to filter it?
• social.png.ts -> included as social.png. Ok, but should it be there?
• [...slug].png.ts -> missing. Good imo, but still inconsistent with above

Hey, there's now a way to configure this not to include the trailing slash. You can configure your astro.config.mjs:

import { defineConfig } from 'astro/config'

export default defineConfig({
    trailingSlash: 'never'
})

Unfortunately that's not the answer. trailingSlash is used to match dev server's behavior to your production host so you can catch errors in links etc. It does affect the URL style used in sitemap, but it's all-or-nothing option and trailing slash is always wrong for file-endpoints like rss.xml.

In my case I'd have to use trailingSlash: 'always' to match my host's behavior while using build.format = 'directory', but the sitemap will then also generate ../rss.xml/ (this issue). A request to that URL will look for .../rss.xml/index.html instead of the .../rss.xml file and return 404

Hey sorry it's taken us a while to get to this one! I'm working on this now.
