chore: Add condition to skip update-fonts workflow on forks

[ryo-manba]

What?

Added a condition to skip the update-fonts workflow for forked repositories.

Why?

To optimize CI resources and prevent extra runs on forks.

How?

By checking the repository name and comparing it with the main repository before executing the workflow.
