Refactor secret management providers and introduce unified handling

- Removed KeePass and SecretStore provider implementations.
- Integrated KeePass and SecretStore as vaults under the SecretManagement provider.
- Added new functions: Get-DSCConfigurationDataCredentialProvider and Set-DSCConfigurationDataCredentialProvider for managing credential providers.
- Implemented Unlock-ConfigurationDataSecretManagementVault to handle vault unlocking with master passwords.
- Updated README to reflect changes in provider usage and examples.
- Enhanced error handling and validation for vault registration and settings.
