~~Elasticsearch tests failed because of https://github.com/mariotoffia/FluentDocker/issues/312 and https://github.com/actions/runner-images/issues/9692.~~ ~~So I made a temporary fix based on https://github.com/mariotoffia/FluentDocker/issues/312#issuecomment-2265612108.~~

@eerhardt, Could you review this PR? Adding CPM will make it easier for us to target .NET 9.

There are a lot of NU1903 warnings in the project when using VS 17.12. you can find an example at https://github.com/Xabaril/AspNetCore.Diagnostics.HealthChecks/issues/2317

I just had 2 comments. Everything else looks good to me.

@adamsitnik @unaizorrilla - any concerns with this?

@Alirexaa @unaizorrilla @sungam3r @adamsitnik - do you know of a timeline when HealthChecks 9.0 would be released?
