[Index Management] If an index template has a default_pipeline, show a link to it

[sabarasaba]

Fixes: #183990

Summary

This PR introduces a link in the index template details flyout, directing users to its associated default pipeline, if one is defined.

In order to test this, you can create an index template with the following command:

PUT _index_template/my-template
{
  "index_patterns": ["my-index-*"],
  "template": {
    "settings": {
      "index": {
        "codec": "best_compression",
        "default_pipeline": "my-default-pipeline"
      }
    },
    "mappings": {
      "properties": {
        "field1": {
          "type": "text"
        },
        "field2": {
          "type": "keyword"
        }
      }
    }
  },
  "priority": 100
}
