Set-PnPList -EnableModernAudienceTargeting only works on Sites created with LCID 1033

[nils-a]

For other sites, the error is "'User Information List' can not be found".

E.g. for 1031 (de-de):

Set-PnPList: Die Liste 'User Information List' ist in der Website mit der URL 'https://....' nicht vorhanden.

The reason here is that the title of the user information list is hard-coded in English:

pnpframework/src/lib/PnP.Framework/Extensions/ListExtensions.cs

Line 2335 in 075fd67

var userInformationList = web.Lists.GetByTitle("User Information List");

This does not for LCIDs where titles have been translated.

Perhaps it is possible to access the resources as with "GetPagesLibrary"

pnpframework/src/lib/PnP.Framework/Extensions/ListExtensions.cs

Line 1309 in 075fd67

var result = Utilities.Utility.GetLocalizedString(context, "$Resources:List_Pages_UrlName", "osrvcore", language);

The value is located in "core.resx" with the key "userinfo_schema_listtitle".

@nils-a It would be great if you could test the PR #1063, if you have the opportunity
