feat(astro): Register astro route provider

[logaretm]

Registers a route provider for Astro from the sentry-route-name meta tag the middleware already injects into every rendered document.

Registered from init() rather than the tracing integration, so route parameterization no longer depends on tracing being enabled.

Unlike the Next.js and Remix providers this is not a matcher. The document only ever describes the page it rendered, so a URL other than the current one resolves to undefined rather than a guess. That guard is also what stops a navigation being named after the route it is leaving.

I checked the soft-navigation behaviour against Astro 5.18 with a throwaway app rather than assuming it. ClientRouter swaps the tag during astro:after-swap, at the same moment location changes, and does not accumulate duplicates, so reading it per call stays correct across client-side navigations and back/forward. It is only stale during a navigation, before the swap, which the current-path guard already excludes.

Part of #23556
