v2.0.0

✨ New major release. This new version should remove the warning about Node 12 being deprecated, along with some improvements to the default behaviour. I also rewrote and improved most of the code.

Added

• Name and version are shown in the cache key. This allows to identify cache
  entries in the cache management UI more easily.

Changed

• Breaking: The action now runs on Node.js 16.
• Breaking: Versions without semver range (e.g. 1.2.3) are now considered
  as exact versions.
• Breaking: Set --locked by default. locked input is no longer
  deprecated.
• Various code improvements and refactoring.
