Getting error for TSLint in response of ng lint even after migrating from TSLint to ESLint and uninstalling the TSLint as well

Question

I have just migrated from TSLint to ESLint and uninstalled the TSLint. But after running the ng lint command in terminal, the error displayed is - Ensure TSLint is installed.

Following is a snippet of few lines I get after running the command ng lint:-

Lint warnings found in the listed files.

Lint errors found in the listed files.

Linting "cat-e2e"... An unhandled exception occurred: Unable to find TSLint. Ensure TSLint is installed.

See "C:\Users\VISHAK~1\AppData\Local\Temp\ng-PWse7M\angular-errors.log" for further details.

I think the issue is in my angular.json file because I still see some traces of tslint in it Please find below my angular.json file:-

I have no idea what to try. My angular version is 8.
