`@gitbook/fontawesome-pro` licensing

@gitbook/embed depends on @gitbook/icons which itself has a runtime dependency on @gitbook/fontawesome-pro.

The package.json for @gitbook/fontawesome-pro specifically has a license value of UNLICENSED.

This causes compliance scanners (e.g. Aikido) to flag it as a critical license violation.

Is this intentional? If so, is there guidance on how this package is licensed?
