Recognize MulanPSL-2.0 license in a project

Description

Even when the project has MulanPSL-2.0 license, it will be recognized as "other" rather than its name.

I see GitLab is using Licensee gem 9.14.1 (https://gitlab.com/gitlab-org/gitlab/-/blob/20d7bd3fcef35c4808caf8d6900973ca597d0cde/Gemfile#L275), and this gem has included MulanPSL-2.0 license since 9.15.2 (see its changelog), shall we upgrade this gem to recognize MulanPSL-2.0 license?

Goal

1. If copy the text of MulanPSL-2.0 manually and create the LICENSE file on root path, it can be recognized correctly rather than others in all plans ( Update: it works now )

Here is another example for Mozilla Public License 2.0, I just copied its text to LICENSE on root path, it's correctly recognized:
