sitemap generation does not include base url

[biscuit314]

Describe the bug

Setting both base: and sitemap: in the site config does not work as expected. The hostname value in the sitemap config is used, but all paths exclude the base: path. Adding the additional path to hostname does not fix the issue.

Reproduction

Configure a site with the following:

export default defineConfig({
    base: '/path/',
    sitemap: {
        hostname: 'https://example.org'
    }
})

Expected behavior

The sitemap generated from the above should all begin with https://example.org/path/... but instead the /path/ part is missing.

It should be hostname: 'https://example.org/path/' (notice trailing slash)

Automatically appending base now will be a breaking change as other projects are already using this pattern.

I was missing the trailing slash. Thank you!
