Horizontal-vertical documentation

@dbeltran could you update https://autosubmit.readthedocs.io/en/latest/usage/wrappers.html?highlight=wrapper with the current syntax?

I think that the SIM POST in Horizontal-vertical and Vertical-horizontal should be changed to SIM, because POST are out of the wrapper.

Then could you add a picture of how a Horizontal-vertical with different jobs inside looks like? For example the SIM+DA of Auto-MONARCH, providing an example with the & notation.
