Fix eslint command to run on all files

[slaweet]

What was the problem?

The eslint command didnt specify which files to run on, so it never checked anything and always passed with usage info:

#!/bin/bash -eo pipefail
yarn eslint --max-warnings=0 --format junit --output-file ./reports/eslint/eslint.xml
yarn run v1.19.1
$ /home/circleci/project/node_modules/.bin/eslint --max-warnings=0 --format junit --output-file ./reports/eslint/eslint.xml
eslint [options] file.js [file.js] [dir]

How did I fix it?

By telling eslint to run on all files in the repo (.)

How did I test it?

I tested it only by running the command locally in my repo, so I'm not sure if this is needed for everyone. Let me know what do you think 🙂
