fix(cloudflare): Make @cloudflare/workers-types an optional peer dependency (#15554)

Redeclare the `@cloudflare/workers-types` package as an
optional peer dependency rather than an optional dependency. With other
SDKs now depending on `@sentry/cloudflare`, we'd pull in the type
package into non-cloudflare projects. (more details:
#15536 (comment)).
