chore(test): Bump svelte dependencies

[Lms24]

Bumps affected sveltekit and node adapter versions in our e2e test apps. Also took the opportunity to pin two ^ version ranges to the specific latest version

File	Package	Old Version	New Version
sveltekit-2-kit-tracing/package.json	@sveltejs/kit	2.31.0	2.49.5
sveltekit-2-kit-tracing/package.json	@sveltejs/adapter-node	^5.3.1	5.5.1
sveltekit-2-svelte-5/package.json	@sveltejs/kit	2.41.0	2.49.5
sveltekit-2/package.json	@sveltejs/kit	2.21.3	2.49.5
sveltekit-cloudflare-pages/package.json	@sveltejs/kit	^2.21.3	2.49.5

Closes #18851 (added automatically)
