Please tell us more about your question or problem

What would you like Renovate to be able to do?

The RPM datasource should be able to read Fedora repositories whose
primary.xml metadata is compressed using Zstandard (primary.xml.zst).

If you have any ideas on how this should be implemented, please tell us here.

Renovate successfully downloads repomd.xml and resolves the referenced
primary.xml.zst, but fails while extracting the metadata.

Describe the bug

Using the RPM datasource against the Fedora 44 updates repository fails with

Failed to extract RPM metadata file from compressed file

Error: incorrect header check
code: Z_DATA_ERROR

The repository uses primary.xml.zst.
