Update the Battery documenation about documentation

[MSECode]

I've updated the branch aligning what decided on the fw and sw side and fixing the timing that were wrong with respect to the code.
Please, @valegagge, take a look to it and if it looks good to you I'll open the PR together with the others for the sw and fw.

Hi @MSECode ,
I fix a typo in the this commit.

Your work is ok, but I suggest you add some improvements in order to make the documentation more clear.

1. change the title.
2. explain that the data of battery are related to the system (robot).
3. create a page with the output of yarp port for BMS. (For the user could be useful have the list of the info exposed by bms and bat even if the device is the same.)
4. add a section for the firmware and out the outcoming data.

I already started updating the documentation in this commit, but it is only a draft. Please update it and fix my work. Thanks! 😸

Obviously, I am available for a chat!
