Multiple Data Paths deprecation is marked as Critical rather than warning

Elasticsearch Version

7.17

Installed Plugins

No response

Java Version

bundled

OS Version

Any

Problem Description

In the upgrade assistant in 7.17 a critical warning is shown saying "Multiple data paths are not supported". This should be downgraded to a warning, as Multiple Data Paths were not removed in 8.0, and thus this should not stop upgrade to 8.0.

See #71205 (comment) for more details.

Steps to Reproduce

Create an elasticsearch deployment with multiple data paths configured. Run the upgrade assistant in 7.17. You will see there is a Critical deprecation message for the multiple data paths feature.

I haven't been able to find this particular deprecation message in Elasticsearch, is it possible it is coming from Kibana directly?

I did find a couple critical deprecations related to this, which I've adjusted in #85952.

Note that the deprecation log had MDP as critical earlier in 7.x but that was fixed in #79463 for 7.16.
