create-next-app: default to ESLint disabled

[leerob]

You can optionally enable it, if desired, but this gives you one less config file by default.

looks like we need to update our prompt tests for this change

[feedthejim]

holding until we further discuss this decision

We're rollin

[hichemfantar]

I don't know about this. we should be encouraging people to write safer and better code.

[r34son]

@leerob Could you please give more details whats motivation for this change?

[leerob]

ESLint is still part of create-next-app. If you would like to continue using it, please do! We are also working on adding support for Biome, and at that point, you will have the option to pick the tool you prefer.

x-ref: #73905

[hichemfantar]

56% of 144 people is such a small sample size to be making such a decision and it's only been a month.

@leerob Would you reconsider if the vote swings another way in the near future?
