pin numpy to < 2.0 until tensorboard cuts a release (facebook#2641)

Summary:
Pull Request resolved: facebook#2641

The latest TB version hasn't incorporated numpy2.0-compatible changes (tensorflow/tensorboard#6869 (comment)), and recently unpinned botorch (D60735276) means Ax CI is now failing. This pins numpy to < 2.0 to prevent issues in CI.
