Sentry plugin - missing key events (parse error, context creation, etc)

Hey there, thanks for the work to date!

I've tried using the `@envelop/sentry` plugin but came to realize it only tracks execution of queries. This means requests which don't reach the execution stage won't be tracked.

Some examples include:
- Failure due to invalid GraphQL syntax
- Failure at context creation time (e.g. auth errors)

---

**To Reproduce**
Steps to reproduce the behavior:
- Create a GraphQL Yoga application using the setup guide
- Add the `@envelop/sentry` plugin
- Make the following GraphQL request

```gql
query query query {
not valid syntax
}
```

**Expected behavior**

The request is tracked in Sentry along with the resulting GraphQLError response.

**Actual behavior**

The request is not tracked.

**Environment:**

Not environment specific

**Additional context**

Happy to contribute!

Start with the @envelop/sentry plugin and reproduce the malformed GraphQL request from the issue, then check how execution events are currently recorded. Done means parse failures and context-creation failures are tracked in Sentry together with the resulting GraphQLError response.
