[BUG] Unit tests issues with node latest published version (21.5.0)

[mgermerie]

Your Environment

• Version used: 2.41.0
• Node version: 21.5.0 (latest published version)
• npm version: 10.2.4

Context

Trying to run unit tests on Node current version (21.5.0) brings warnings and errors :

• In test/unit/bootstrap.js, line 26, we set navigator.userAgent property which has been made read-only in node 21.1.0 (see this commit. This can be easily fixed with a test :

if (!global.navigator) {
    global.navigator = { userAgent: 'firefox' }
}

• When applying the previous fix, we get a deprecation warning :

(node:29868) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.

Steps to Reproduce (for bugs)

1. Download and use node 21.1.0
2. run npm install
3. run npm run test-unit
4. You can see the deprecation message after applying the fix in #

Possible Cause/Fix/Solution

The first point is fixed in #2255.

Can confirm that this issue starts with node >= 21.0.0, latest LTS (20.x.x) is not impacted.
