Add configurations for linting scripts and add global ignores

Related issue

It seems like the default recommended javascript config was being applied to our scripts files and this was causing issues with lefthook trying to lint the files

Description

I added a specific config for our _scripts folder so we can still use eslint for those files. I also moved some of the ignores to the top of the script which serves as a global ignores (it will apply to all rule below)

Screenshots

Before:

• add console.log to a file in _scripts (ex: getShakaLocales.js)
  
• try to commit:
  
  After:
• commit successful

Could you please optimise the ignore patterns according to the docs: https://eslint.org/docs/latest/use/configure/ignore

• When ignoring directories it is best to add a / to the end of the pattern so that ESLint knows that it is a folder and can skip scanning the directory entirely.
• The dist, _scripts, .github and node_modules directories only exist in the same directory as the eslint.config.mjs file, so we don't need recusive patterns for those.

You can test the performance of the patterns by calling ESLint without passing any files on the command line, that way it gathers the files to check based on the config file: yarn eslint or npx eslint

Sorry for only commenting this now, but I wanted to test it on my computer before I commented. The eslint docs mention that **/node_modules/ is on the default ignores list so we don't have to add it ourselves.

[...]. This pattern is added after the default patterns, which are ["**/node_modules/", ".git/"].
