chore(deps): update eslint to 10.8.1

[MikeMcC399]

• closes Update to current ESLint 10.x #848

Situation

• The repo is configured for ESLint 9.22.0
• ESLint 9.x transitioned into EOL on 2026-08-06
• Linting config is external through "@yarnpkg/eslint-config": "^3.0.0" pinned to @yarnpkg/eslint-config@3.1.0

Change

Update
eslint to 10.8.1
@yarnpkg/eslint-config to 3.1.1

The script lint is reduced to "lint": "eslint".

https://eslint.org/docs/latest/use/command-line-interface

You can also omit the file arguments and ESLint will use ".".

Verification

corepack yarn install
corepack yarn lint

Other

corepack yarn install causes a peer dependency warning from eslint-plugin-react@7.37.5 which is not compatible with ESLint 10, however since there are no *.jsx React source files in Corepack, linting causes no error.

It is not a barrier to upgrading to the supported version of ESLint (10.x).
