[ISSUE] databricks_library resource does not support workspace files

[tigerhawkvok]

See https://docs.databricks.com/en/libraries/workspace-files-libraries.html

The databricks_library provider should have a workspace block taking a path to the workspace file.

This is particularly relevant given DBR15's ability to support requirements.txt files

Sample syntax:

        library {
            # https://registry.terraform.io/providers/databricks/databricks/latest/docs/resources/job#library-configuration-block
            workspace {
                path = databricks_workspace_file.requirements.workspace_path
            }
        }

If no support is planned (or not planned for a while), the documentation should be updated to reflect this rather than the conspicuous absence.

(The same happens to be true for volume files, too, which could be repeated verbatim as above with a text replacement. https://docs.databricks.com/en/libraries/volume-libraries.html )
