[agdimech]

Support disableDefaultLicenses property on the Monorepo to prevent licenses from being generated for all projects by default.

Fixes #736

Hi @agdimech
I have updated PDK to v0.23.30 and it seems the licences are still being created, here is my .projenrc.ts

const monorepo = new MonorepoTsProject({
  ...baseOptions,
  deps: ["@aws/pdk@0.23.30", "cdk-nag", "yaml", "zod@^3.22.4"],
  devDeps: ["@aws/pdk@0.23.30",],
  name: "pdk",
  packageManager: javascript.NodePackageManager.PNPM,
  projenrcTs: true,
  gitignore: [
    "!**/cdk.out/cdkgraph/diagram.png",
    "!**/cdk.out/cdkgrapgh/threat-model.tc.json",
    "!**/config.yml",
    "!bin/*.ts",
    "!lib/*.ts",
    "**/__snapshots__",
    "**/*.drawio.bkp",
    "**/cdk.out",
    "**/data",
    "**/dist",
    "steampipe/**/*.csv",
    "steampipe/**/*.txt",
  ],
  vscode: true,
  licensed: false,
  prettier: true,
  prettierOptions: {
    settings: {
      trailingComma: TrailingComma.ALL,
      singleQuote: false,
      printWidth: 120,
      semi: false,
    },
  },
});

git diff, yields, after running pdk at the root of my monorepo:

Untracked files:
  (use "git add <file>..." to include in what will be committed)
	projects/backup/LICENSE
	projects/github-runners/LICENSE
	projects/monitoring/LICENSE
	projects/pipeline/LICENSE

HI @nkhine-shieldpay - you need to use the licenseOptions: {disableDefaultLicenses: true} on the monorepo to prevent default licenses from being created.
