Subject: [PATCH] Optimise github actions (#363)

* Hash mix files with glob.

* NPM and dialyzer caching.

* Fix yaml.

* Incorrect hashFiles call.

* Fix blockscout npm path.

* Build dialyzer cache in build cache phase.

* Actually do dialyzer in it's own job to prevent blocking other jobs.

* Add meaningful names.

* Remove sweeping windows log.

* Remove test branch.

* Use env vars for otp and elixir release versions.

* Fix templating.
