alpine-image for ASP.NET Core 3.1.8 is missing

[jehof]

We generally use the basic alpine-Image of ASP.NET CORE. But since 3.1.8 the tag 3.1.8-alpine is missing. Is this intentional? What tag should be used instead?

This is the list of existing 3.1.8 tags, taken from https://mcrflowprodcentralus.data.mcr.microsoft.com/mcrprod/dotnet/core/aspnet?P1=1599802058&P2=1&P3=1&P4=d2h2d6ybZGX%2F3r038Ud6sHD%2FqKX3fLjrBil%2B%2BxkbHrk%3D&se=2020-09-11T05%3A27%3A38Z&sig=WaObCJtY6cCj2pnFgoRUzASOrHZ3%2FD5Jpf12IMtlKLQ%3D&sp=r&sr=b&sv=2015-02-21:
