Lumen 8 compatibility

[HimanshuM]

Tested on Lumen version 7 & 8
Following error is thrown:
Declaration of Nbj\Cockroach\Grammar\Query\CockroachGrammar::compileUpdateColumns($values) must be compatible with Illuminate\Database\Query\Grammars\Grammar::compileUpdateColumns(Illuminate\Database\Query\Builder $query, array $values)
This can be fixed by changing the prototype of the method.

I'll see if I can open a PR for this.

This appears to be in master with 626613a - so probably could be closed?
