### Summary   
<!-- Insert your summary of changes below. Minimum 10 characters

This pull request updates the `es-metadata.yml` file to use schema
version 1.0.0 and adds provider information for better metadata
management.

Metadata and schema updates:

* Updated the `schemaVersion` from `0.0.1` to `1.0.0` to reflect a new
schema version.
* Added a `providers` section specifying the `InventoryAsCode` provider
with version `1.0.0`, and included associated metadata such as
`isProduction` and `accountableOwners`.
