tls: typo correction in error comment

Old style errors are being migrated to internal/errors.js, however, due
to deprecation of _tls_legacy.js, it isn't worth the effort to migrate
and potentially force users to update their code for this error change.

This comment clarifies the reason why this error is not migrated.
Previous commit had a typo, needed to change the word depreciated to
deprecated.
