Github Actionsでbotによるアイコン付きのCommitをする方法
public
趣味プロジェクトのため、2.の github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> を採用した

1. github-actions <github-actions@github.com>
README.md推奨の方法
2. github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>
どこにも推奨はされていないものの、アイコンもリンクも動作する
下記の通り、 github-actions[bot]@users.noreply.github.com でも動作するようだ
bash
git config --local user.email "github-actions[bot]@users.noreply.github.com" git config --local user.name "github-actions[bot]"

>@Linda_pp: github-actions bot のメアドの 41898282+github-actions bot @​users​.noreply​.github​.com の数字ってどこから来たのかと思ったらユーザ ID なのか https://t.co/V8FDjSCM0s
41898282 は、https://api.github.com/users/github-actions%5Bbot%5DのユーザIDらしい

参考
>I think this would be a nice feature. It would also lead to a more consistent appearance of commits created by GitHub Actions. I'm currently wondering which email address and username I should use for the time being.
>
> The README.md suggests github-actions <github-actions@github.com>. However, this email is not recognized by the platform. GitHub displays the author of the commit with the generic icon and without a link.
>
> A thread in the GitHub Support Community suggests github-actions[bot] < 41898282+github-actions[bot]@users.noreply.github.com >. This seems to work nicely. The author of the commit has the same icon and name as GitHub Actions everywhere else. The link goes to https://github.com/features/actions as I would expect. I'm just wondering if there is any caveat since it is not promoted in the README.md.
>
> Most repositories I found seem to use GitHub Action <action@github.com>. I don't know where this is comming from. GitHub seems to link it to some user but clicking on the user opens a 404-page. The icon and name doesn't match what is usually shown for GitHub Actions.
>
> If there is no caveat for the second option, I would suggest that the checkout action configures Git accordingly if none of both options is already set. (Alternatively, GitHub's runners could be updated to use this configuration.)
>@nwtgck_ja: TIPSとしては、GitHub Actionsのボットがコミットしたようにするには"github-actions bot @users.noreply.github.com"をメールアドレスにするといける。
