Support remove transforms with array based paths

[jonsnyder]

Description

In the AEP Web SDK we use remove transforms with array based paths. See https://github.com/adobe/reactor-extension-alloy/blob/9cebcefd8e09376b9eff7d01f5fae4f4e0b5e036/extension.json#L122

These remove transforms with array based paths do not work in the sandbox. This PR fixes that.
