feat: add legacy main attribut for legacy node applications

[Slashgear]

Why

Some of our apps are not yet compatible with esm natively and can't use the module exported files on server.
In order to to recompile them locally and as they are exported directly, let's add the legacy main attribute for retrocompatibility.

Recent package will use exports syntax and ignore the main one

How

• add main on package that have CommonJS exported assets
