chore(deno): Stop testing types (#14738)

I noticed that after
#14729, now tests
started failing 😬

The reason:

* We run `deno check ./build/index.mjs`
* This checks the types, but we now do not inline those anymore into the
generated `./build/index.d.ts` file
* Instead, we just import them from `@sentry/core`
* Now `deno check` downloads the latest version of core into a local tmp
folder and uses this for checking
* But there are different exports there than locally, leading to test
failures 😬

this PR simple kills the type tests - not sure if we need them/they are
needed, but I can't think of a different way to make this work, there
isn't really a way (as far as I see?) to tell `deno check` to consider a
dependency from a local path instead 😬
