Update gl/canvas and configure dependabot

[bkeepers]

1. Remove yarn.lock, ignore package manager lock files - this allows local development environments to test the latest compatable releases, and to use whichever package manager they chose
2. Enable dependabot for keeping dependencies up to date - this enables (re-enables?) dependabot and adds basic configuration.
3. Update gl and canvas to lastest releases - gl@5 doesn't have pre-built binaries for the latest node releases.

Please merge this. I believe this is needed in order to install editly on modern computers

I npm installed your fork (npm install github:sailplan/editly#deps) and it fixed my gl installation problem. Thank you!
