Add managed module: google/cel-spec/test

[jafaircl]

This is slightly different since google/cel-spec is already available. But, the test types are not. Only cel/expr is available on the BSR. Implementing CEL conformance tests requires the test package as well.

Mandatory

Where is the source code for the Managed Module?

https://github.com/google/cel-spec/tree/master/proto/test/v1

Yes

Optional

Does this module have other module dependencies/imports?

It would have the same dependencies as the other cel-spec packages

Based on the repository's release process, do you prefer syncing by SemVer releases or by git commit SHA?

It should follow the same process as the other cel-spec packages

Additionally, is there a sensible initial reference to sync from?

It should follow the same process as the other cel-spec packages

Do you think this module is widely used by the community, and is not already provided on the BSR by the owners?

Not sure how widely used it would be. The rest of the cel-spec package is already on the BSR
