Update Homebrew now that 'cask' is deprecated

[alanhogan]

See https://brew.sh/2020/12/01/homebrew-2.6.0/

tl;dr 'cask' should be removed from installation commands.

Should it be brew install qlmarkdown --cask ?

Homebrew/homebrew-cask#114520
qlmarkdown has been renamed to toland-qlmarkdown,
so it should be brew install toland-qlmarkdown --cask.

@vidhill the --cask flag doesn’t seem to be necessary.

I was getting mixed up, there are two repos/projects, https://github.com/toland/qlmarkdown and this,

When someone runs brew cask install qlmarkdown it installs https://github.com/sbarex/QLMarkdown version?

When someone runs brew cask install qlmarkdown it installs https://github.com/sbarex/QLMarkdown version?

Without researching it, I am not sure what version brew install qlmarkdown installs, but brew cask install qlmarkdown will not install anything. It gives this error:

Error: `brew cask` is no longer a `brew` command. Use `brew <command> --cask` instead.

When I ran brew install qlmarkdown --cask, it installed https://github.com/sbarex/QLMarkdown.

Interesting… Hmm. Well, the REAMEs over there do have the updated brew syntax, so that’s good.
