Issue in the `[Operational Observability] Highest Failure Jobs` dataset in `LakeFlow System Tables Dashboard v0.1.lvdash.json`

[pradipbasak]

In both the usage_with_cost and most_recent_jobs CTEs, one of the filter condition in the WHERE sub-clause is the following:-

if(
      :param_workspace = '<ALL WORKSPACES>',
      true,
      workspace_id = :param_workspace
)

The problem with this is, workspace_id expects a BIGINT but when we select a workspace from the dashboard it passes the workspace_name, not the workspace_id. Therefore, the Highest Failure Jobs visual in the Operational Observability tab renders with a TYPE_MISMATCH error. It explicitly says that STRING type can't be type-casted to BIGINT.
