[text-auditor] Fix `sucess` typo family in CEF/CyberArk user-facing descriptions

## Text Improvements

The following user-facing text issues were found in the repository. Each is a low-effort fix.

### 1. Typo family: `sucess` → `success` in ArcSight outcome descriptions

**Why:** `sucess` is an unambiguous typo and appears repeatedly in user-facing field descriptions and rendered package docs.

**Verified occurrences (completeness pass):**

**File:** `packages/cef/data_stream/log/fields/fields.yml` (line 99)
**Current text:** `Outcome of the event (e.g. sucess, failure, or attempt) (ArcSight).`
**Suggested fix:** `Outcome of the event (e.g. success, failure, or attempt) (ArcSight).`

**File:** `packages/cef/data_stream/log/fields/fields.yml` (line 121)
**Current text:** `Outcome of the event (e.g. sucess, failure, or attempt) (ArcSight).`
**Suggested fix:** `Outcome of the event (e.g. success, failure, or attempt) (ArcSight).`

**File:** `packages/cyberark_pta/data_stream/events/fields/cef.yml` (line 154)
**Current text:** `Outcome of the event (e.g. sucess, failure, or attempt) (ArcSight).`

**File:** `packages/cyberark_pta/data_stream/events/fields/cef.yml` (line 157)
**Current text:** `Outcome of the event (e.g. sucess, failure, or attempt) (ArcSight).`
**Suggested fix:** `Outcome of the event (e.g. success, failure, or attempt) (ArcSight).`

**File:** `packages/cef/docs/README.md` (line 418)
**Current text:** `| cef.extensions.categoryOutcome | Outcome of the event (e.g. sucess, failure, or attempt) (ArcSight). | keyword |`
**Suggested fix:** `| cef.extensions.categoryOutcome | Outcome of the event (e.g. success, failure, or attempt) (ArcSight). | keyword |`

**File:** `packages/cef/docs/README.md` (line 426)
**Current text:** `| cef.extensions.destinationNtDomain | Outcome of the event (e.g. sucess, failure, or attempt) (ArcSight). | keyword |`

**File:** `packages/cyberark_pta/docs/README.md` (line 185)
