Draft: Exclude user-defined CI/CD variables from cache archiver env
Azure cache uploads fail if a user defines an invalid
AZURE_STORAGE_KEY
as a CI/CD variable because Go Cloud attempts to use
that instead of the temporary AZURE_SAS_TOKEN
.
Since the cache archiver shouldn't need user-defined variables, we modify the shell to omit them.
Closes #27448
