Minor Changes

• #9846 9b78c992750cdb99c40a89a00ea2a0d1c00877d7 Thanks @ktym4a! - Adds a new configuration option prefix that allows you to change the default sitemap-*.xml file name.

  By default, running astro build creates both sitemap-index.xml and sitemap-0.xml in your output directory.

  To change the names of these files (e.g. to astrosite-index.xml and astrosite-0.xml), set the prefix option in your sitemap integration configuration:

  import { defineConfig } from 'astro/config';
  import sitemap from '@astrojs/sitemap';
  export default defineConfig({
    site: 'https://example.com',
    integrations: [
      sitemap({
        prefix: 'astrosite-',
      }),
    ],
  });
  

  This option is useful when Google Search Console is unable to fetch your default sitemap files, but can read renamed files.
