Track reverting to upstream eslint after temporary fork

[sergeyklay]

A forked version of eslint (@ledsun) was temporarily used when upgrading from 9.39.2 to 10.0.0 due to pending upstream fixes (see related issues: jsx-eslint/eslint-plugin-react#3977, jsx-eslint/eslint-plugin-react#3979).

Follow-up required

Switch back to the mainstream eslint package as soon as upstream issues are resolved and the fork is no longer needed.
