[BUG] Searching for index patterns does not filter list on v2.11.1

[lyradc]

Background
This issue was first identified on version 2.11.0 and was resolved on PR 5484. The fix was back-ported to 2.11, however the issue persists.

Steps to Reproduce
I am able to reproduce this issue on https://playground.opensearch.org/app/data-explorer/discover as well as from a new cluster created via docker-compose.

To reproduce the issue on playground.opensearch.org:

1. Navigate to https://playground.opensearch.org/app/data-explorer/discover and search for an index pattern.

2. Note matches are bold, although index patterns with no match remain in the drop-down list.

To reproduce the issue via docker-compose:

1. Start with the sample docker-compose.yml found at https://opensearch.org/docs/latest/install-and-configure/install-opensearch/docker/#sample-docker-composeyml

2. Update the image tags to '2.11.1' for nodes and dashboard services.
   image: opensearchproject/opensearch:latest
   to
   image: opensearchproject/opensearch:2.11.1

3. Once the new cluster is up create three index patterns:

*
security*
security-audit*

4. Navigate to discover and search for 'audit'. Note the other two entries remain visible despite no match.

Expected Behavior
When text is entered into the index patterns drop-down the list should filter out index patterns with no partial match.

In our environment we have hundreds of index patterns. It is unusable for our users to scroll through so many entries without filtering.

After discussing with Barani Bikshandi and Ashwin Pc I learned this fix was not included in the 2.11.1 release.
