Submitting formula to Homebrew

Would y'all mind if I submitted a Homebrew formula for `passage` to [`homebrew/core`](https://github.com/Homebrew/homebrew-core)? I've written a basic formula here:

```
class Passage < Formula
desc "Fork of password-store that uses age instead of GnuPG"
homepage "https://github.com/FiloSottile/passage"
url "https://github.com/FiloSottile/passage/archive/1.7.4a1.tar.gz"
version "1.7.4a1"
sha256 "0705ff409d4a6160ade347e63be623170da023ec199116dac83b406a18f7e0d7"
license "GPL-2.0-or-later"
head "https://github.com/FiloSottile/passage.git", branch: "main"

depends_on "age"
depends_on "gnu-getopt"
depends_on "qrencode"
depends_on "tree"

def install
system "make", "PREFIX=#{prefix}", "WITH_ALLCOMP=yes", "BASHCOMPDIR=#{bash_completion}",
"ZSHCOMPDIR=#{zsh_completion}", "FISHCOMPDIR=#{fish_completion}", "install"
inreplace "#{bin}/passage",
/^SYSTEM_EXTENSION_DIR=.*$/,
"SYSTEM_EXTENSION_DIR=\"#{HOMEBREW_PREFIX}/lib/passage/extensions\""
end

test do
(testpath/".passage").mkdir
system Formula["age"].opt_bin/"age-keygen", "-o", ".passage/identities"
system bin/"passage", "generate", "foo.bar"
assert_predicate testpath/".passage/store/foo.bar.age", :exist?
end
end
```
