[release/7.0-staging][wasm] CI: Fix EAT/AOT tests build

[radical]

The builds for wasm EAT/AOT tests are broken because building System.Format.Cbor.Tests fails with:

@radical - Reminder: Code Complete for the August Release is tomorrow Monday July 10th. If you intend to include this fix in that release, please make sure to merge it before 4pm because that's when I'll start the staging merge process into internal.

I approved it and added the required label. Merge if the CI looks good.
