chore: track terraform modules in telemetry (#15450)

Addresses https://github.com/coder/nexus/issues/35.

This PR:

- Adds a `workspace_modules` table to track modules used by the
Terraform provisioner in provisioner jobs.
- Adds a `module_path` column to the `workspace_resources` table,
allowing to identify which module a resource originates from.
- Starts pushing this new information into telemetry.
