fix(brew): add assume_yes support

[uwuclxdy]

What does this PR do

This PR makes topgrade pass -y to brew cask and formula steps when assume_yes = true.

Fixes #2088

Standards checklist

• The PR title is descriptive
• I have read CONTRIBUTING.md
• Optional: I have tested the code myself, with the relevant tools installed. If yes, add Topgrade's output of the relevant steps.
• If this PR introduces new user-facing messages they are translated

AI involvement

None.

@adbario could you test this pretty please?
