Fix plugin configuration path (#1304) (#1342)

The dashboard has references to an old path that does not exist anymore:
`plugins/opensearch-security/securityconfig/config.yml`.  It was
replaced by `config/opensearch-security/config.yml` in this commit:

opensearch-project/security@b44d7ea

Fix the last occurences of `plugins/opensearch-security/securityconfig`.
