Fix run suggestion in metadata panel to include namespace

[AhdraMeraliQB]

Description

The metadata panel will suggest a run command when a node in the pipeline is suggested. However, if the node is within a namespace, this suggestion will not work.

Important note: The formatting of the command is also inconsistent with other Kedro resources. As a result of kedro-org/kedro#2014 command suggestions should now follow the format kedro <command> --<flag>=value1,value2.

Steps to Reproduce

1. Run kedro run on a new spaceflights project
2. Run kedro viz
3. Open metadata panel

4. Run the suggestion under "Run Command:"

Expected Result

The pipeline should run until the specified node.

Actual Result

The pipeline throws an error.

ValueError: Pipeline does not contain nodes named ['split_data_node']. Did you mean: 
['data_science.active_modelling_pipeline.split_data_node', 
'data_science.candidate_modelling_pipeline.split_data_node']?

Your Environment

Kedro version: 0.18.4
Kedro Viz version: 5.2.0

Triage assessment: looks like we need to update package/kedro_viz/models/flowchart.py. Search for run_command.
