vcpkg not writing to cache with GitHub Actions

[rustyconover]

Describe the bug

It seems that sometimes vcpkg doesn't store the built binaries to the GitHub Cache. While some triples are working as expected, others don't seem to write any binaries to the cache at all.

Environment

• OS: Linux GitHub Runner

To Reproduce

Steps to reproduce the issue:

-- Using source at /vcpkg/buildtrees/utf8-range/src/v5.26.1-47a5094a20.clean
-- Found external ninja('1.10.2').

This happens for all packages in the build. Other triplets work as expected with the same configuration.

Expected behavior

We would expect the GitHub Actions cache to be used, with the binaries successfully stored in it.
