  This PR implements the  dataplex-get-data-asset  tool for the Dataplex
(Knowledge Catalog) source, allowing users to fetch detailed
configuration
  metadata for a single Data Asset.

  Changes overview:

- Dataplex Source: Implemented GetDataAsset to retrieve details for a
specific asset by location, data product, and asset ID. The response
maps the
  resource URI, labels, and access group configurations.
- New Tool: Created the dataplex-get-data-asset tool exposing locationId
,
  dataProductId , and  dataAssetId  parameters.
  - Tests:
      - Added unit tests for tool configuration parsing.
- Added integration tests asserting successful metadata retrieval and
      authorization checks.
  - Documentation: Created the reference page for the tool, updated the
  Dataplex source guide, and added it to the main capabilities list.

  This PR implements the  dataplex-get-data-asset  tool for the Dataplex
(Knowledge Catalog) source, allowing users to fetch detailed
configuration
  metadata for a single Data Asset.

  Changes overview:

- Dataplex Source: Implemented GetDataAsset to retrieve details for a
specific asset by location, data product, and asset ID. The response
maps the
  resource URI, labels, and access group configurations.
- New Tool: Created the dataplex-get-data-asset tool exposing locationId
,
  dataProductId , and  dataAssetId  parameters.
  - Tests:
      - Added unit tests for tool configuration parsing.
- Added integration tests asserting successful metadata retrieval and
      authorization checks.
  - Documentation: Created the reference page for the tool, updated the
  Dataplex source guide, and added it to the main capabilities list.

This PR implements the dataplex-create-data-product tool for the
Dataplex
(Knowledge Catalog) source. Since creation is a Long-Running Operation
(LRO),
the tool immediately returns the operation ID to allow asynchronous
polling.

  Changes overview:

- Dataplex Source: Implemented CreateDataProduct which starts the
creation
  process and returns the immediate LRO details.
  - New Tool: Created the  dataplex-create-data-product  tool exposing
locationId , dataProductId , displayName , description , ownerEmails ,
  and  accessGroups  parameters.
  - Tests:
      - Added unit tests for tool configuration parsing.
- Added integration tests verifying LRO triggers and access
restrictions.
  - Documentation: Created the reference page for the tool, updated the
  Dataplex source guide to cover LRO polling, and added it to the
  capabilities list.
