Describe the proposed feature.

When enabling the SDK plugin, the relative script (sdk.plugin.zsh) can load the sdk-init.sh script if the env SDKMAN_DIR is missing.

Describe alternatives you've considered

SDK can be loaded automatically by adding the following in the sdk.plugin.zsh

if [[ -z "$SDKMAN_DIR" ]]; then
  if [[ -d "$HOME/.sdkman" ]]; then
    [[ -s "$HOME/.sdkman/bin/sdkman-init.sh" ]] && source "$HOME/.sdkman/bin/sdkman-init.sh"
  fi
fi
