Added several features and bugfixes to ReportUserAssignedLicenses-MgGraph.PS1

Changes:

Reformat code for better readability with VSC
Make all paths variable
Fix date so it can be used in all language formats
Add snipped for alternative authentication
Added display for license errors (e.g. user has license group assigned but there's no free license)
Account unused now computed by both last interactive sign in and last non-interactive sign in
Last license change is displayed too
Fixed wrong output if license is assigned direct and per group (previously, it was only displayed in the group)
Fixed disabled plans not displaying correctly
