feat!: upgrade eslint process w/ workflow testing

[erisu]

Motivation and Context

• Use Cordova's ESLint package
• Applied both manual and automatic changes.
• Added GitHub Actions Workflow to run liniting

I changed my mind on having a lint matrix.

Linting should not matter on which environemnt or node is being used.

If we introduced node testing, then we should have a matrix for that.
