message: Fix formatting issue in eager compatibility description for Adam.
diff: @@ -119,16 +119,19 @@ class Adam(optimizer_v2.OptimizerV2):
  amsgrad: boolean. Whether to apply AMSGrad variant of this algorithm from
  the paper "On the Convergence of Adam and beyond".
  name: Optional name for the operations created when applying gradients.
  - Defaults to "Adam". @compatibility(eager) When eager execution is
  - enabled, `learning_rate`, `beta_1`, `beta_2`, and `epsilon` can each be
  - a callable that takes no arguments and returns the actual value to use.

  + Defaults to "Adam".
  **kwargs: keyword arguments. Allowed to be {`clipnorm`, `clipvalue`, `lr`,
  `decay`}. `clipnorm` is clip gradients by norm; `clipvalue` is clip
  gradients by value, `decay` is included for backward compatibility to
  allow time inverse decay of learning rate. `lr` is included for backward
  compatibility, recommended to use `learning_rate` instead.
