Validation: Put more meaningful message in case invalid bundle path

With this PR now end user will observe more meaningful message to run
`crc setup` in case want to use the default bundle.
```
$ ./crc config set bundle /foo/bar
Value '/foo/bar' for configuration property 'bundle' is invalid, reason: /foo/bar is invalid or missing, run 'crc setup' to download the default bundle

$ ./crc start -b /foo/bar
/foo/bar is invalid or missing, run 'crc setup' to download the default bundle
```
