Describe the bug

Currently, the Xeon CPU model names displayed by btop are truncated after the first space, as a result, their version numbers are omitted from btop's displayed CPU model name. For example, E3-1230 v6 is displayed as E3-1230 instead. For Intel Xeon CPUs, many have similar model names and are distinguished only by a version number. They're completely different CPUs, the version numbers are part of their proper model names and should not be omitted. In this case, the Intel Xeon E3-1230 is a Sandy Bridge CPU released in 2011, but the Intel E3-1230 v6 is a Kaby Lake CPU released in 2016.

To Reproduce

Launch btop on a Xeon CPU with a model name that ends with v2, v3, v4, v5, etc. The last word (the version number) is omitted from the displayed model name.

Expected behavior

The last word (version number) of the Xeon CPU's model name should be preserved.
