Update HTML/CSS Documentation about linters-config

@arthurborgesdev happy you solved your issue, yes it's not needed to have the package.json (which what npm init will do) to run the command, as long as it's installed in your machine, you can even install it globally using -g so you don't have to install on each project.

could you explain more/give an example @arthurborgesdev?

When I run the commands before initializing the package.json file, I get errors, see:

1 - Run npm install --save-dev [email protected] (Prompt in the documentation):

2 - The package is installed, but it does not generate a package.json file per si:

3 - Although... as I can see now, the npx hint . run correctly even without running npm init at the beginning... strange. I don't know what I did on the first try that made me switch to the npm init approach...

I will close the issue, thank you!
