In https://github.com/flutter/flutter/pull/82577, I landed a version
bump of package shelf and package flutter_template_images. This local
override should have been part of that patch but was missed in the
checkin.

The version bumps themselves happened in the previous patch; this just
ensures we don't accidentally 'upgrade' back to version 1.0.2.

Windows package identifiers are globally unique strings, typically a
GUID. These are required for templates that require a Windows package
name as described in
https://docs.microsoft.com/en-us/windows/win32/appxpkg/appx-portal

Fixes https://github.com/flutter/flutter/issues/82587

* Add cmdline tools to docker image.

This is to make the flutter doctor new checks to pass.

Bug: https://github.com/flutter/flutter/issues/82565

* Use correct package name.

* Add version to sdkmanager command.

shelf 1.1.2 -> 1.1.4
flutter_template_images 1.0.2 -> 3.0.0
