Improve the error message for missing modules

Currently, the error that is produced in case of a missing module is not really user friendly:

node:internal/process/esm_loader:74
    internalBinding('errors').triggerUncaughtException(
                              ^
Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'not-existing-module' imported from /Users/matteo/temp/a.mjs
    at new NodeError (node:internal/errors:363:5)
    at packageResolve (node:internal/modules/esm/resolve:698:9)
    at moduleResolve (node:internal/modules/esm/resolve:739:18)
    at Loader.defaultResolve [as _resolve] (node:internal/modules/esm/resolve:853:11)
    at Loader.resolve (node:internal/modules/esm/loader:89:40)
    at Loader.getModuleJob (node:internal/modules/esm/loader:242:28)
    at ModuleWrap.<anonymous> (node:internal/modules/esm/module_job:73:40)
    at link (node:internal/modules/esm/module_job:72:36) {
  code: 'ERR_MODULE_NOT_FOUND'
}

Rust for example provide more user friendly errors:

error[E0432]: unresolved import `crate::constants`
 --> src/primes.rs:5:12
  |
5 | use crate::constants::{FNUM, PNUM, SMAX};
  |            ^^^^^^^^^ maybe a missing crate `constants`?

Note that our errors do not list which line the dependency was not specified.

What do you think? I think it would improve things long term.

Commencez par suivre le chemin du module manquant dans internal/process/esm_loader et internal/modules/esm/resolve et loader, en utilisant la sortie ERR_MODULE_NOT_FOUND montrée comme référence. L’issue ne nomme pas de test et ne prescrit pas de formulation exacte ; le travail serait considéré comme terminé lorsqu’un message d’erreur plus clair, identifiant l’endroit où la dépendance a été demandée, aura été défini et implémenté, avec une couverture pour le message obtenu.
