  GetEnvironmentName

  This partial returns either the configured or the default build environment
  name.

  The four options for setting the build environment name (ordered by priority)
  are:
  1. The "HUGO_ENV" environment variable.
  2. The "env" site config theme parameter.
  3. Setting the "useHugoEnv" site config theme parameter to true, which will
     use the value of ".Hugo.Environment" for the build environment name.

     The default environment name for the  "hugo server" command is
     "development", and the default for the "hugo" build command is
     "production". The environment name can be configured via the
     "--environment" flag, such as "hugo --environment test".
  4. Use the default build environment name.

  @return build environment name.
