Add generic_private_key to secret scanning generic types list

[Copilot]

The secret scanning API calls were missing generic_private_key from the hardcoded list of generic secret types, causing these alerts to be excluded from CSV exports.

Changes

• Added generic_private_key to the generic secret types filter in three functions:
  • get_repo_ss_alerts() - repository-level scanning
  • get_org_ss_alerts() - organization-level scanning
  • get_enterprise_ss_alerts() - enterprise-level scanning

The generic types list now includes all 10 non-provider patterns:
ec_private_key, generic_private_key, http_basic_authentication_header, http_bearer_authentication_header, mongodb_connection_string, mysql_connection_string, openssh_private_key, pgp_private_key, postgres_connection_string, rsa_private_key

# Before
generic_secret_types = "password,ec_private_key,http_basic_authentication_header,..."

# After  
generic_secret_types = "password,ec_private_key,generic_private_key,http_basic_authentication_header,..."

Original prompt

Non-provider patterns - Ensure each of these generic secret types are in the list:

Provider Token Description Precision
Generic ec_private_key Elliptic Curve (EC) private keys used for cryptographic operations High
Generic generic_private_key Cryptographic private keys with -----BEGIN PRIVATE KEY----- header High
Generic http_basic_authentication_header HTTP Basic Authentication credentials in request headers Medium
Generic http_bearer_authentication_header HTTP Bearer tokens used for API authentication Medium
Generic mongodb_connection_string Connection strings for MongoDB databases containing credentials High
Generic mysql_connection_string Connection strings for MySQL databases containing credentials High
Generic openssh_private_key OpenSSH format private keys used for SSH authentication High
Generic pgp_private_key PGP (Pretty Good Privacy) private keys used for encryption and signing High
Generic postgres_connection_string Connection strings for PostgreSQL databases containing credentials High
Generic rsa_private_key RSA private keys used for cryptographic operations High
