Description

The Learn More section in plugins/gem-team/README.md linked to a local LICENSE file that does not exist in that directory, leading to a 404 when followed on GitHub. This updates the link to point to the license file in the plugin's upstream repository (mubaidr/gem-team), matching the pattern used by the adjacent Documentation and Contributing links.

Type of Contribution

• Update to existing instruction, prompt, agent, plugin, skill, workflow, or canvas extension.

Additional Notes

Before this change, the relative link resolved to a non-existent path in this repository and produced a 404 error. The updated target resolves to the upstream license with HTTP 200.
