… generate larger bipartite graphs.
Fixes sagemath#38618.
`genbg` was limited to bipartite graphs with up to 32 vertices. Using
`genbgL`, we can go to 64 vertices.
Note that in the doctests, we use the form `...genbg...` as currently
lines starting with `>A` contain `genbgL` while lines starting with `>E`
contain `genbg`. using this formulation, we are on the safe side.
On the way, we fix the documentation of `digraphs.tournaments_nauty()`.
