[LOTP] Add NuGet

# Description of the LOTP tool

NuGet is a package manager for .NET, designed to facilitate the creation, sharing, and consumption of useful code

# Configuration files

```
NuGet.config
```

# Documentation
https://learn.microsoft.com/fr-fr/nuget/reference/nuget-config-file

# Additional notes

NuGet config can be placed at solution level (or any parent of the solution ...), user level, and computer level.
When multiple nuget.config are found, the config is actualy "merged" into an "effective" nuget.config.

The next details will blow your mind.
Once you merged (or not merged) your nuget.config, and have several feeds for package (typical usage is public/private/internal feed for package), you may think that the order of package feed in the list is important.

But it's not the case.

The "fastest" feeds win. Whatever if it's private/public/first/last.

Start by reviewing the repository’s existing tool entries and the NuGet.config documentation linked in the issue. Add NuGet using the project’s established format, documenting its configuration locations, merged settings, and feed behavior; done means the new entry matches neighboring tools and accurately reflects the referenced documentation.
