Make preact and @preact/signals optional peer dependencies (#3400)

### Background

Make `preact` and `@preact/signals` optional peer dependencies in the `@shopify/ui-extensions` package, allowing consumers to use the package without requiring these dependencies if they're not needed. Consumers should be able to pull in their own version explicitly. Previously these were set to `optionalDependencies` with `"*"` which resolved to the latest version.
