Informational: some used NuGet packages have reported vulnerabilities

[vbaderks]

Hi CrypToolProject,

When building your project in Visual Studio 2022 17.12.3 I noticed the following warnings:

NU1902: Package 'BouncyCastle' 1.8.5 has a known moderate severity vulnerability, GHSA-6xx3-rg99-gc3p
NU1903: Package 'Google.Protobuf' 3.6.1 has a known high severity vulnerability, GHSA-77rm-9x9h-xj3g
NU1903: Package 'Newtonsoft.Json' 12.0.3 has a known high severity vulnerability, GHSA-5crp-9r3c-p9vr

Note 1: if needed, I could create a PR to upgrade these NuGet packages to a version that has these issues resolved.
Note 2: Your project doesn't have a Contributing Guidelines or a Security policy listed, so I hope opening an issue like this is ok.

Hiho,
Thanks for the hint -- we replaced the mentioned libs with the newest versions. Also, we removed nuget so far from CT2 since it broke our build process. Adding full nuget support is a future task. Also, we will add contribution guidelines.
Kind regards,
Nils
