fix: remove object-hash dependency from home plugin

The object hash doesn't work if the component props include React
components such as icons. This is true for example the HomepageToolkit
component. Removed the hashing of the component props
completely as the hash is totally optional to be used as a key in the
CustomHomepageGrid.
