CalloutVariantsにおける'wip'と'experimental'のTitleを翻訳

[kenji-arata]

CalloutVariantsのうち、Titleが未翻訳であるものを翻訳しました。

• 'Experimental Feature' -> '実験的機能'
• 'Under Construction' -> '準備中'

CalloutVariantsの中で他にもTitleが英語のものがありましたが、それぞれ以下の理由で今回は翻訳対象外と判断しました。

• deprecated: Deprecatedという表現は開発者の中では一般的で、そのままの方が正しくニュアンスが伝わりやすいと思ったため。
• canary: 現状使用されておらずどのような文脈で使用されているのか参考情報がなかく、誤った翻訳を避けたかったため。

Details

Only the gzipped size is provided here based on an expert tip.

First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.

Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 10% or more, there will be a red status indicator applied, indicating that special attention should be given to this.

問題ないと思います、ありがとうございます。

メニューUIなどデザイン面で敢えて英語を残す判断をしている部分もあるのですが、これはそれには該当しないと思います。
