v0.8.0-alpha.5

This release includes a number of fixes and improvements for the experimental support for CUE modules first released in v0.8.0-alpha.1.

Modules

A new cue mod get command is added, which can add a new module dependency, update an existing one, or downgrade an existing one as long as it does not cause any conflict.

The cue/load package has a new Config.Env struct field to provide the environment variables used to load CUE modules from registries.

A new cue help registryconfig documentation section has been added, explaining how $CUE_REGISTRY works as well as the configuration file schema it supports.
