[Suggestion] Deprecate npmOptions and buildManagerOptions options in favor of a single packageManagerInstallOptions option

[bertdeblock]

packageManagerInstallOptions is more in line with the new packageManager option.

packageManagerInstallOptions type:

packageManagerInstallOptions: string[] | (defaultOptions: string[], scenario: Scenario) => string[];

When the user provides string[], we don't include the default options like we do now. If the user wants to make sure the default options are included as well, they must provide a function and spread in the default options manually.
