Issue crc-org#588 Remove bundle version from version section.

Without this `version` output look following, which doesn't make sense
since now Openshift version is part of version command and contain
this detail.

```
$ ./crc version
version: 1.0.0-beta.2-4.1.11+a0732c0
OpenShift version: 4.1.11 (not embedded in binary)
```

With this change, now it looks bit sane.

```
$ ./crc version
version: 1.0.0-beta.2+a0732c0
OpenShift version: 4.1.11 (not embedded in binary)
```
