Avoid check of the ratchetFrom branch when Spotless not invoked

Currently, Spotless (Gradle Plugin) performs a check for the presence of the ratchetFrom branch on every command execution. This includes instances where Spotless-specific commands aren't called, which can lead to unnecessary checks, and adds the workaround (e.g. git fetch depth:0) for all cases.

Could we refine the ratchetFrom functionality so that it checks for branch presence only when a Spotless command is actually invoked?

I believe this adjustment could be beneficial for users who integrate Spotless into their development workflows, ensuring that the tool remains as efficient and unobtrusive as possible.

まず、Spotless Gradle Plugin における ratchetFrom の処理と、Spotless 固有のコマンドがどのように呼び出されるかを追跡します。Spotless コマンドの実行時にのみブランチの存在チェックが行われ、通常の Gradle コマンドではそのチェックと、それによって生じる fetch-depth の回避策が行われないことを確認します。
