sort-keys option allowLineSeparatedGroups is not supported

[SimonGolms]

Unfortunately, the allowLineSeparatedGroups option introduced with eslint@8.21.0 (eslint/eslint#16138) for sort-keys is also not supported and conflicts with the current documentation in the README:

For available config options, see official sort-keys reference. All options supported by sort-keys, besides minKeys, are supported by sort-keys-fix.

I appreciate your work and the plugin and it would be great if the option is also supported and close feature request #4 with it. If not, it would be helpful to update the relevant section in the README so that users of this package are aware of it.

In case other users come over here and want to use this option, eslint-plugin-sort-keys-plus seems to be a maintained fork of this plugin which already supports the option.
