Add Brave browser as available option

[dapperdancer]

I would like to add Brave as an option to change default browsers.
I found the list of acceptable browsers following links in the readme and it looks like Brave is not on the list.

Hi @dapperdancer

If Brave is registered as a HTTP handler with macOS upon installation it should appear in the list automatically.

Without Brave installed on my local machine:

./defaultbrowser
  iterm2
  kitty
* chrome
  firefoxdeveloperedition
  safari

With Brave installed on my local machine:

./defaultbrowser
  iterm2
  browser
  kitty
* chrome
  firefoxdeveloperedition
  safari

The challenge is that Brave registers as: browser

@kerma I believe this issue can be closed
