[Rule] GROUP rules

[bhirsz]

Robot Framework 7.2 introduce new syntax: GROUP. We need to add rules that will cover it.

Proposals:

1. GROUP without name

GROUP
    Keyword Call
END

2. Nested GROUPs

GROUP    Named
    GROUP  At some point we may recommend not using nested groups / use custom keywords instead
        Keyword Call
    END
END

3. Too many parameters - already handled by parsing error

    GROUP    Too    many    values
        Fail    Not run
    END

4. Empty group

GROUP    Empty group
END

5. Invalid syntax (for some reason parsing error does not catch it):

GROUP    Group without end
```

How about GROUP with a single keyword in the body?

GROUP  foo
    Do only one thing
END

And maybe a rule for too deeply nested stuff. You can do this without groups, but groups make it easier to create deep nesting:

GROUP  foo
  IF  something
    FOR  i  IN  range(10)
      GROUP  bar
        ...
      END
    END
  END
END

GROUP  foo
    Do only one thing
END

yes, typically we should avoid it - we can add len rule for it (configurable if needed). Also too big group rule

any ideas to get this published?

It should be implemented first :) currently I'm handling ongoing issues after 6.0 release, but if not someone else, then I could take a look ina upcoming weeks. If you have ideas for different group rules then also please share.
