Fixes a linear algebra transpose typo in the markdown text of Section 3 (Bayesian Linear Regression).
The formula for the prior (marginal) variance of the latent function was written as an outer product ($\alpha^2 \boldsymbol{\phi}(\boldsymbol{x}_*) \boldsymbol{\phi}(\boldsymbol{x}_*)^\top$), which yields a matrix. This PR corrects the order to an inner product ($\alpha^2 \boldsymbol{\phi}(\boldsymbol{x}_*)^\top \boldsymbol{\phi}(\boldsymbol{x}_*)$) to correctly evaluate to a scalar variance, matching the actual code implementation in the subsequent cell.
