Delete deprecated index settings "archived.*"

Is your feature request related to a problem? Please describe.
When migrating from ElasticSearch to OpenSearch (via the snapshot restore path), indexes can/will be restored with deprecated index settings, e.g. archived.index.lifecycle.name. However, when applying an index policy and switching its state, the ISM fails with the following info: "unknown setting [archived.index.lifecycle.name] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"

Describe the solution you'd like
It would be wonderful, to either let the user delete deprecated "archived" settings or fix the problem for the ISM (the ISM state change should work independently from existing deprecated "archived" settings.

Describe alternatives you've considered
Currently, only a complete reindex will fix these ISM failures. However, reindexing is time and CPU intensive.

Additional context
OpenSearch 1.2.3
Migration from ElasticSearch 7.10.2

Start by reproducing the snapshot restore from Elasticsearch 7.10.2 into OpenSearch 1.2.3, then apply an ISM policy and switch its state with an archived.index.lifecycle.name setting present. Investigate the restore and ISM paths; done means deprecated archived settings can be removed or the ISM state change succeeds without reindexing.
