Version bump that should have been done by dependabot

@MichaelSimons - Is it possible to reference system.security.cryptography.pkcs.7.0.2 as an external nuget? This worked just fine for 7.0.0 - however I do not see 7.0.2 being supported: https://github.com/dotnet/source-build-reference-packages/tree/main/src/referencePackages/src/system.security.cryptography.pkcs Is that planned to be added? (as 7.0.0 and 7.0.1 have known vulnerabilities)

source-build-reference-packages is a self servicing repo. If you need a new package added which it appears like it is, you can add it yourself following these instructions. If you need any help I will be glad to help.

New version added to dotnet/source-build-reference-packages - however to be able to use it we need to reference the latest version - that is currently blocked by #8893

@dotnet/source-build-internal - Adding System.Security.Cryptography.Pkcs/*7.0.2* to prebuild as a temporary workaround, so that we can update the vulnerable package.

The proper solution will require SRBP update, which will require update to arcade 8 - so this will need a bit of time
