cli_pkg 1.0.0-beta.6 changelog

1.0.0-beta.6 #

Breaking change: Chocolatey now uses the choco CLI to build and deploy packages, rather than re-implementing its logic in Dart. In particular:
- The pkg-chocolatey-build task has been renamed to pkg-chocolatey-pack to match the CLI's naming scheme.
- The pkg-chocolatey-pack and pkg-chocolatey-deploy tasks must be run in an environment with the choco command available.
Add a pkg-chocolatey command that builds an un-archived Chocolatey package directory.
Rather than releasing binary snapshots on Chocolatey, compile the source code to compile native executables on users' machines.
Add a chocolateyFiles getter that returns the files that should be included in the Chocolatey package.
Depend on the correct version of pre-release Dart SDKs from Chocolatey packages.

Add a pkg.npmDistTag getter that controls the distribution tag for an npm release.
Add a pkg.homebrewCreateVersionedFormula getter that controls whether the Homebrew release creates a new formula or updates an existing one.
Run pub publish --force so it doesn't hang forever.
Properly parse GitHub repositories from HTTP URLs ending in .git.
Drop support for Mac OS ia32 packages, since Dart 2.7 doesn't support them anymore.

Add a cli_pkg/testing.dart library to make it easier for users to efficiently and reliably test their executables.

Add a pkg-standalone-dev task for building a script that can be invoked for testing.
Fix a bug where the version variable wouldn't be set for certain executables.
