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

+### Version file
+
+A version file is specified via input `version-file` (e.g.`.tool-versions`). This
+allows not having to use YML input for versions, though the action does check (and
+will exit with error) if both inputs are set.
+
+**Note**: if you're using a version file, option `version-type` is checked to be `strict`,
+and will make the action exit with error otherwise.

+The following version file formats are supported:

+          hexpm-mirrors: https://cdn.jsdelivr.net/hex

+
+Alternatively, you may try `cdn.jsdelivr.net/hex` if `builds.hex.pm` fails:
