Why?

To provide encryption compatibility with our Java Encryption Sample,

1. Closes

Not applicable

2. How was this tested:

Tested in a different project to validate encryption is cross SDK compatible. Ran dotnet tests

3. Any docs updates needed?

Can you confirm what the behavior regarding tag placement is with https://github.com/temporalio/samples-typescript/tree/main/encryption, https://github.com/temporalio/samples-python/tree/main/encryption, and https://github.com/temporalio/samples-go/tree/main/encryption? At quick glance there is no tag on the latter two? Is it possible to confirm compatibility with this implementation and those 3 (ignoring Java for now)? I just want to confirm that .NET is the outlier and not Java.

Looks like this PR makes this sample work with multiple other-language samples repos. Marking approved. Merge at will.
