A few minor changes required:

In includes/class-woocommerce.php, below public $version = '3.5.3'; add

public $cc_version = '0.1.0';

In includes/api/v2/class-wc-rest-system-status-v2-controller.php, add

'cc_version' => WC()->cc_version,

in the return array in get_environment_info() (line 614 approx).

In includes/admin/views/html-admin-page-status-report.php (approx line 67), change as follows:

<tr>
  <td data-export-label="CC Version"><?php esc_html_e( 'Classic Commerce version', 'classic-commerce' ); ?>:</td>
  <td class="help"><?php echo wc_help_tip( esc_html__( 'The version of Classic Commerce installed on your site.', 'classic-commerce' ) ); /* phpcs:ignore WordPress.XSS.EscapeOutput.OutputNotEscaped */ ?></td>
  <td><?php echo esc_html( $environment['cc_version'] ); ?></td>
</tr>
<tr>
  <td data-export-label="WC Version"><?php esc_html_e( 'WooCommerce version', 'classic-commerce' ); ?>:</td>
  <td class="help"><?php echo wc_help_tip( esc_html__( 'The version of WooCommerce installed on your site.', 'classic-commerce' ) ); /* phpcs:ignore WordPress.XSS.EscapeOutput.OutputNotEscaped */ ?></td>
  <td><?php echo esc_html( $environment['version'] ); ?></td>
</tr>
