skaffold does not handle tilde sign (home directory) under kubectl > manifests

Related to: https://github.com/GoogleContainerTools/skaffold/issues/2123 and https://github.com/GoogleContainerTools/skaffold/pull/2233

### Expected behavior

skaffold should be able to use manifests from files in the home directory

### Actual behavior

skaffold fails with:

invalid skaffold config: skaffold config file "skaffold.yml" referenced file "~/.secrets/timescaledb/timescaledb-secrets.yml" that could not be found.

Verify that file "~/.secrets/timescaledb/timescaledb-secrets.yml" referenced in config "skaffold.yml" exists and the path and naming are correct.
