Cask with same name as formula leads to formula being upgraded/installed instead of cask

[ROpdebee]

The docker cask is an example. Trying to update it through cu leads to a warning from brew:

Warning: Treating docker as a formula.

after which it installs the docker formula. neo4j is another example.

brew has a --cask flag to disambiguate, so a manual update works:

brew upgrade --cask docker

I presume cu isn't passing this flag to brew yet.

Versions:

Homebrew 3.6.20-167-g7a5f614
Homebrew/homebrew-core (git revision be29dbf85c2; last commit 2023-01-27)
Homebrew/homebrew-cask (git revision a8fb94a787; last commit 2023-01-28)

Seems like this was already fixed a few years back (#177) but for some reason it's happening again. The --cask flag appears to work properly now though.

Yeah, also noticed that, thx for reporting. Fix is on its way.
