fix(dashboard): do not delete the dashboard report (#3669)

* Do not delete the dashboard report

For the past two years I have wondered why I would get "Report could not be found..." error on the dashboard when performing this command:

```sh
dotnet tool run dotnet-stryker --reporter dashboard --open-report:dashboard --version main --dashboard-api-key ******
````

Today I looked at the code and it turns out that the HTTP client performs a DELETE request on the report when all the mutants are tested, obviously deleting it!

Note: this regression was introduced in #2563.

* Call PublishReport _after_ PublishFinished

Since PublishFinished performs a DELETE on the report
