Oss 133 new detector vault approle auth for hashicorp

[SyedAliHamad]

Description:

This PR introduces a new detector for HashiCorp Vault AppRole authentication credentials.

Detection:
Keyword Filtering: scans for related keywords to identify relevant data chunks
Multi-Component Pattern Matching: Uses regex to find three required components:

• role_id: hexadecimal UUID format
• secret_id: hexadecimal UUID format
• vault_url: HashiCorp Cloud URLs matching *.hashicorp.cloud pattern

all 3 components creates verifiable combination results

Deduplication: Ensures each unique credential combination is tested only once to prevent redundant API calls

Verification:
Validates credentials against Vault's /v1/auth/approle/login endpoint using detected URLs

200 OK: Credentials are valid and active
401/403: Invalid credentials or insufficient permissions
404 Not Found: AppRole auth method not enabled

Testing:
Pattern Tests: Comprehensive validation of formats, keyword detection, and URL pattern matching
Integration Tests: Live API verification with both active and inactive credentials

Checklist:

• Tests passing (make test-community)?
• Lint passing (make lint this requires golangci-lint)?
