The dll:serve script in the generated package does not work

[pomek]

📝 Provide detailed reproduction steps (if any)

1. Generate a new package (you can use the npm version of the tool).
2. Change cwd as the script suggests.
3. yarn run dll:serve prints a lot of strings (see: yarn run test prints unexpected characters ckeditor5#11092).

✔️ Expected result

yarn run dll:serve works.

$ http-server ./ -o sample/dll.html
Starting up http-server, serving ./

http-server settings:
CORS: disabled
Cache: 3600 seconds
Connection Timeout: 120 seconds
Directory Listings: visible
AutoIndex: visible
Serve GZIP Files: false
Serve Brotli Files: false
Default File Extension: none

  http://192.168.0.11:8080
Hit CTRL-C to stop the server
Open: http://127.0.0.1:8080/sample/dll.html

❌ Actual result

❓ Possible solution

• When using yarn, adding the resolutions key in pkg.json fixes the problem (see: ckeditor/ckeditor5@a4100bf).

📃 Other details

• Once you generate a new package, you can modify its package.json and reinstall dependencies.

• To avoid executing dll:serve, you can see a version of the colors package in node_modules/ or lock files (package-lock.jsonoryarn.lock`)

• A proper fix is needed in packages/ckeditor5-package-generator/lib/templates/package.json

• Node: v14.18.1

Due to a bug in colors library, http-server stopped working (which broke wide range of repositories, not just our stuff), but thankfully, fix in http-server is being worked on. In the meantime, temporary fix is to modify packages/ckeditor5-package-generator/lib/templates/package.json as follows:

For yarn, add:

"resolutions": {
  "colors": "1.4.0"
},

For npm, you need to keep in mind that you have to use npm 8.3.0 or later, as it introduced overrides that is equivalent to yarn's resolutions. Also keep in mind, that latest LTS Version of node.js includes npm 8.1.2, which does not have this function yet, and current version is required instead. If you have required version, add:

"overrides": {
  "colors": "1.4.0"
},
