feat: add dataset dimensions to chart records

[mlbrgl]

Add ETL dataset dimensions to Algolia search index

This PR adds ETL dataset dimensions to the Algolia search index to enable faceting by dataset namespace, version, name and producer. These dimensions are extracted from variable catalog paths and added to chart, explorer, and multi-dimensional view records. Producers come from the DB.

The changes:

• Extract dataset namespace, version, and name from catalog paths
• Extract producers from the DB
• Add these dimensions to all chart types in the search index
• Configure Algolia to include these new fields in attributes for faceting
• Add unit tests for the catalog path parsing function

Testing guidance

Verify that chart records in the Algolia index now include the new fields:

• datasetNamespaces
• datasetVersions
• datasetProducts
• dataProducers

The easiest is to use the preview feature added in the next PR up the stack #5940.

• Does the staging experience have sign-off from product stakeholders?
