Blocking the merge as I'm building from this branch and testing the new error messages locally.

When running command on a malformed plugin executable file on Windows:
./notation.exe plugin install --file ./malformed-plugin/azure-kv/notation-azure-kv.exe, the command returns following error message:

Error: plugin installation failed: failed to get metadata of new plugin: failed to execute the get-plugin-metadata command for plugin azure-kv: fork/exec ./malformed-plugin/azure-kv/notation-azure-kv.exe: This version of %1 is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher..
Please ensure the plugin is executable and meet the installation requirements on the windows/amd64.

On linux:

Error: plugin installation failed: failed to get metadata of new plugin: failed to execute the get-plugin-metadata command for plugin azure-kv: fork/exec test-plugin/malformed-plugin/azure-kv/notation-azure-kv: exec format error.
Please ensure the plugin is executable and meet the installation requirements on the linux/amd64.

These error messages are quite verbose though, can we improve them? (contents starting with fork/exec are already in the DEBUG log)
