Exception while fetching SQ config

[epiphany20]

Description

When running on Ubuntu 20.04:

dotnet sonarscanner begin /k:"HelloWorld" /d:sonar.host.url=http://localhost:9000 /d:sonar.login=admin /d:sonar.password=admin

I receive the following exception:

20:04:10.057 Fetching analysis configuration settings...
20:04:21.859 Failed to request and parse 'http://localhost:9000/api/rules/search?f=repo,name,severity,lang,internalKey,templateKey,params&ps=500&activation=false&qprofile=AXTgCizl8dTovacH3i-F&p=21&languages=cs': The remote server returned an error: (400) .

Apparently a page beyond some internal limit is loaded to retrieve config data. It says on the SQ page when opening the URL in a browser:

"Can return only the first 10000 results. 10500th result asked."

It looks like GetInactiveRules() in sonar-scanner-msbuild/src/SonarScanner.MSBuild.PreProcessor/SonarWebService.cs is not resilient errors. As a workaround, maybe it could just always return an empty list. I couldn't get this to build, however.
