@JamesHenry fyi as #6162 is upcoming

[Zamiell]

that shouldn't really affect this pr

[JamesHenry]

What's the deal with this diff?

[Zamiell]

no idea, it showed up as different when I copy pasted the md file from the main branch. are they different kind of spaces or something? I tried copy pasting them into this site and they both show up as normal spaces, so I'm not really sure

[JoshuaKGoldberg]

git checkout main -- packages/website/blog/2023-07-09-announcing-typescript-eslint-v6.md fixed it for me. 🤷

[JamesHenry]

Now that #6162 is finally up to date and green, we can potentially skip this PR as the same field is added in that PR for yarn v3

[JoshuaKGoldberg]

Looks like #6162 is pretty close! I'll merge this in the meantime to give Zamiell contribution credit in the Git history / on github dot com. 😄

[JoshuaKGoldberg]

Blurgh, I didn't think to change the PR title to chore:, and now it's in the release log. Ah well 🙃
