asdf-parse-tool-versions

Parses asdf .tool-versions file extracting version information.

Returns a JSON string as output with this format:

{"golang":"1.12.5","ruby":"2.7.0"}

Each tool has it's own key where value is the value in the .tool-versions file.

The action also exports all versions as environment variables with the format <tool>_VERSION (i.e. GOLANG_VERSION).
