yaegi import fails with go 24.1

[rcoreilly]

Describe the bug

this happens when running our yaegicore update make script, only with go 24.1, not with 23.7:

cd /Users/oreilly/go/src/cogentcore.org/core/yaegicore/basesymbols (from: {FileDirPath})
packages.go:1193: internal error: package "errors" without types was imported from "fmt"
failed to run "yaegi extract fmt strconv strings math time log/slog reflect path/filepath: exit status 1"
goal run failed: context canceled

https://pkg.go.dev/golang.org/x/tools/go/packages

packages.go file contains line:

 	log.Fatalf("internal error: package %q without types was imported from %q", path, lpkg)
		panic("unreachable")
	})

unclear at this point why hitting this with 24 and not 23 and what versions are being used etc.

How to reproduce

run it.
