Add brew install support

[ashitaprasad]

API Dash is currently not available on Homebrew. Contributors can help us in the following ways:

1. Provide Step by step details on how to create a build and release it.
2. CI/CD pipeline which prepares and publishes the build on FlatHub whenever pubspec.yaml version is bumped.

Developers are requested to add (1) in https://github.com/foss42/apidash/blob/main/doc/dev_guide/packaging.md

Once (1) is completed (2) can be taken up.

Hey @ashitaprasad I'd like to take this if no one's working on it currently

I have previously distributed apps with homebrew (it was a CLI application written in Go ), the usual process was to build and create a new release everytime I push an update with a tag and using GoReleaser and Github Actions I would easily distribute the apps (for Homebrew).

• For this we need 2 things 1 tap repository which will store the .rb files required.
• We'll need to setup auto releases for APIDash.
