Add notebook-governance-sempy: tenant-wide lakehouse table inventory using SemPy

[dataassets1]

Pull Request (PR) description

Supersedes #509 — same tool, rewritten with Semantic Link (SemPy) instead of raw Fabric REST API calls. All review feedback from #509 and #483 is incorporated.

Adds samples/notebook-governance-sempy/ — the first of a planned set of governance notebooks built on SemPy / the Fabric REST API. This notebook builds a tenant-wide inventory of all lakehouse tables and registers it as a Spark temp view (fabric_lakehouse_inventory) for direct SQL querying.

Why the rewrite: sempy.fabric handles auth, pagination, and retries natively, reducing the code to a fraction of the REST version while staying aligned with the library Microsoft ships in Fabric notebooks.

Added

• samples/notebook-governance-sempy/ — notebook + README (usage, output schema, example queries, known limitations)

Task list

• The PR represents a single logical change.
• CHANGELOG entry — N/A, repository has no CHANGELOG.md
• Local clean build — N/A for notebook samples
• Comment-based help added/updated (quick tutorial in the notebook header)
• Examples appropriately added/updated (example queries in README)
• Unit tests — N/A for notebook samples
• Integration tests — manually validated in a live Fabric tenant (temp view created, failure summary reported)
• Documentation added/updated (README.md)
• Code follows the contribution guidelines

Pull request overview

Adds a new SemPy-based governance notebook sample that inventories lakehouse tables tenant-wide (scoped to the executing identity) and exposes the results as a Spark temp view (fabric_lakehouse_inventory) for ad-hoc SQL querying inside Microsoft Fabric notebooks.

Changes:

• Added get-tables.py to enumerate workspaces → lakehouses → tables via sempy.fabric and publish the inventory as a Spark temp view.
• Added README documentation describing usage, output, example query, and known limitations.
