Matthew Flatt cff766ab84 change Git package references to use default branch
If a Git package source does not include "#" followed by a ref, then
use the branch/commit designated by a server as the default branch or
commit (i.e., the one for the "HEAD" symref), instead of assuming the
branch "master".

This is technically a backward-incompatible change to the
interpretation of Git package sources, but explicit branch
specification continues to work the same. For the forseeable future,
to support recent versions, packages in a branch other than "master"
will still need to be specified using the branch name, such as
including "#main" at the end of the package source. Eventually,
relevant versions of Racket will support the new default.

Relevant to #3672

Racket is a general-purpose programming language and an ecosystem for language-oriented programming.

This repository holds the source code for the core of Racket plus some related packages. The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.

Quick Start

Pre-built versions of Racket for a variety of operating systems and architectures, as well as convenient source distributions are available at

https://download.racket-lang.org

Racket comes with extensive documentation, including several tutorials. You can read all of this documentation, as well as documentation for third-party packages at

https://docs.racket-lang.org
