ESLINT: Create rule that warns if using "unsafe" redirect or goto

[Macludde]

Because of paraglide we want to use i18n.resolveRoute when using goto or redirect (to preserve language tag). We now have wrapper for this (see #310), we should have an eslint rule that complains if you try to use goto or redirect from $app/navigation or sveltekit-flash-message/server respectively. Because we have flash-messages, I think it should complain about using redirect from @sveltejs/kit as well.
