Update linters script

[Diegogagan2587]

Implemented Changes:

we have updated the script lint in package.json in order to run all installed linting tools on this project with
a single command, son when you type npm run lint in your console the next linting tools will run:

• eslint
• styleint

This will avoid the developer having to run npx eslint "**/*.{js,jsx}" and npx stylelint "**/*.{css,scss}" separately in
the console, but run them together instead with a single command npm run lint which is easier to remember.

Pull Request Rejection

Dear Diego,

Thank you for your contribution to the project! I appreciate the time and effort you've put into this pull request. However, after careful review, I've decided not to merge it at this time.

Reasons for Rejection

1. The command npm run lint is working well, but I've found a little issue:
   If there are errors in both JS and CSS files, that command shows only JS errors, so the tester or user needs to fix all the JS errors and re-run the npm run lint command to see the CSS errors. This behavior can introduce misunderstandings because the user can think that all the JS & CSS linters errors are solved when there are still some CSS errors.
   Before introducing JSX linters errors:
   
   as you can see, the CSS errors are being shown
   After introducing JSX linters errors:
   
   as you can see, the CSS errors are NOT being shown

Next Steps

I encourage you to address the feedback provided and resubmit the pull request. Feel free to reach out if you have any questions or need further clarification.

Optional Suggestions

1. Review this warning 29:6 warning React Hook useEffect has missing dependencies: 'API_URL_BASE' and 'token'. Either include them or remove the dependency array react-hooks/exhaustive-deps
   at this component /home/dani/WD/Book-a-concert-front-end/src/pages/DeleteConcertPage.jsx
   when running this command npm run lint

Thank you again for your contribution and understanding.

Best regards,
Dani

@danifromecuador Thanks so much for noting that out, I think that yeah, it's important to see at once all the linting errors to get a better perspective about what we are doing wrong, so I 'll correct, thanks! and regarding to your optional suggestion is something I'm working on in a different branch, thanks!

@danifromecuador After updating the script, now it will show both ESlint and Stylint results, I have added errors only in my local repo to generate some failings in linting tools to verify this behavior:

If there is something else let me know! thanks @danifromecuador
