Fix doc format issue in enable_eager_execution (#19116)

* Fix doc format issue in enable_eager_execution

This fix tries to address the issue raised in 19022 where
the doc of `tf.enable_eager_execution` was not well formatted.
It seems the additional empty lines may confuse the doc generator.
This fix fixes with proper alignment and removal of empty lines.

This fix fixes 19022.
