Repository Naming Conflict Between rules_jsonnet and rules_rust

[deblasis]

What

When using rules_jsonnet in a module that also uses rules_rust, there is a naming conflict for the rust host tools repository. This results in a build error due to duplicate repository generation.

Proposed Solution

The fix requires specifying a unique repository name for the rust host tools in rules_jsonnet to avoid the naming conflict. A PR will be submitted shortly with this change.
