Fix post -main-merge issue (#213)

* Fix OTP version null check

* Revert "Fix OTP version null check"

This reverts commit 2c433c16ac.

* Check that the resolved versions contain the spec.

* Only perform semver version resolution when spec is not an rc and version-type is not strict

* Move version inclusion check to the end of the function, when we may have prepended a 'v'

* Refactor function return

* Add test case for strict version resolving a spec that is no available version

+## Alternative hex.pm mirrors
+
+It is possible to use alternative hex.pm mirror(s), in their declared order, with
+option `hexpm-mirrors`. By default, the action will use `builds.hex.pm`.
+To use other alternative mirrors, add one per line, as shown below.
