[FEATURE]Remove Integration content folder in favour of dynamic catalog loading

[YANG-DB]

Is your feature request related to a problem?
Since we've finally moved integration content & release artifacts into the catalog repo - we also need to remove the duplicate content away from this repo in favour of a dynamic process that loads the most up-to-date integrations assets from the catalog release folder

What solution would you like?

1. remove the https://github.com/opensearch-project/dashboards-observability/tree/main/server/adaptors/integrations/__data__/repository folder
2. add github flow that copies the catalog release assets into a designated folder for each repository [dashboards-observability] release process
3. add code that loads the catalog assets into the savedObjects during plugin startup

Do you have any additional context?

• [Enhancement] Set up release directories for each integration and setup latest tag for each integration release opensearch-catalog#155
• https://github.com/opensearch-project/opensearch-catalog/blob/main/docs/integrations/Release.md

I know this was being worked on last June, I'm not sure what the current timeline is on it.

This probably also would pair well with the release directory mentioned in opensearch-project/opensearch-catalog#155
