[MR Widget Eng] Remove License Compliance MR widget references to old approval_status codes

Once #335868 (closed) lands we need to then go back and update work done in !75341 (merged) for the MR widget extensions.

Change:

const APPROVAL_STATUS_TO_ICON = {
  allowed: EXTENSION_ICONS.success,
  approved: EXTENSION_ICONS.success,
  denied: EXTENSION_ICONS.failed,
  blacklisted: EXTENSION_ICONS.failed,
  unclassified: EXTENSION_ICONS.notice,
};

        const licenseSections = [
          ...(groupedLicenses.denied?.length > 0 || groupedLicenses.blacklisted?.length  > 0 ? [{
            header: s__('LicenseCompliance|Denied'),
            text: s__(
              "LicenseCompliance|Out-of-compliance with the project's policies and should be removed",
            ),
            children: groupedLicenses.denied || groupedLicenses.blacklisted,
          }] : []),
          ...(groupedLicenses.unclassified?.length > 0 ? [{
            header: s__('LicenseCompliance|Uncategorized'),
            text: s__('LicenseCompliance|No policy matches this license'),
            children: groupedLicenses.unclassified,
          }] : []),
          ...(groupedLicenses.allowed?.length > 0 || groupedLicenses.approved?.length > 0 ? [{
            header: s__('LicenseCompliance|Allowed'),
            text: s__('LicenseCompliance|Acceptable for use in this project'),

            children: groupedLicenses.allowed || groupedLicenses.approved,
          }] : []),
        ];

            text: s__('LicenseCompliance|Acceptable for use in this project'),
            
            children: groupedLicenses.allowed,
          }] : []),
        ];

const APPROVAL_STATUS_TO_ICON = {
  allowed: EXTENSION_ICONS.success,
  denied: EXTENSION_ICONS.failed,
  unclassified: EXTENSION_ICONS.notice,
};
