feat: give finer control over trailing slash handling

[sebmahe]

🆒 Your use case

In the context of an ecommerce website, I'm using trailing slashes for category pages (ex: notebooks) and no trailing slashes for product pages (ex: macbook-air).

At this time, this configuration is not possible with @nuxtjs/sitemap. The configuration option trailingSlash is only set site-wide.

🆕 The solution you'd like

I'm using a multi-sitemap configuration. I'm wondering if the trailingSlash option can be moved at the sitemap level ?

export default defineNuxtConfig(
	sitemap: {
		sitemaps: {
			categories: {
				sources: [ '/api/sitemaps/categories' ],
				trailingSlash: true
			},
			products: {
				sources: [ '/api/sitemaps/products' ]
				trailingSlash: false
			},
		},
	},
)

🔍 Alternatives you've considered

In my context, sitemaps are generated with dynamic sources like illustrated in the config sample above. Each endpoint output locations with the wanted trailing slash or without trailing slash.

If the locations can be left untouched : my problem would also be solved.
