chore: remove call to taskname.Generate in dbgen (#22040)

I was trying to figure out why `goleak` was complaining about a dangling
http2 connection goroutine in tests. Turns out that `taskname.Generate`
will call out to Anthropic if an API key is set, and we're calling it in
`dbgen`. Modified to use testutil method instead.
