/**
 * <p>Modifies a launch template. You can specify which version of the launch template to
 *             set as the default version. When launching an instance, the default version applies when
 *             a launch template version is not specified.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, ModifyLaunchTemplateCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, ModifyLaunchTemplateCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * // import type { EC2ClientConfig } from "@aws-sdk/client-ec2";
 * const config = {}; // type is EC2ClientConfig
 * const client = new EC2Client(config);
 * const input = { // ModifyLaunchTemplateRequest
 *   DryRun: true || false,
 *   ClientToken: "STRING_VALUE",
 *   LaunchTemplateId: "STRING_VALUE",
 *   LaunchTemplateName: "STRING_VALUE",
 *   DefaultVersion: "STRING_VALUE",
 * };
 * const command = new ModifyLaunchTemplateCommand(input);
 * const response = await client.send(command);
 * // { // ModifyLaunchTemplateResult
 * //   LaunchTemplate: { // LaunchTemplate
 * //     LaunchTemplateId: "STRING_VALUE",
 * //     LaunchTemplateName: "STRING_VALUE",
 * //     CreateTime: new Date("TIMESTAMP"),
 * //     CreatedBy: "STRING_VALUE",
 * //     DefaultVersionNumber: Number("long"),
 * //     LatestVersionNumber: Number("long"),
 * //     Tags: [ // TagList
 * //       { // Tag
 * //         Key: "STRING_VALUE",
 * //         Value: "STRING_VALUE",
 * //       },
 * //     ],
 * //     Operator: { // OperatorResponse
 * //       Managed: true || false,
 * //       Principal: "STRING_VALUE",
 * //       HiddenByDefault: true || false,
 * //     },
