Update Model Energg Demand and Fix Problem of Submodels

[Margherita-Capitani]

In this pull request, the following are proposed:

• A new methodology for calculating energy demand by introducing the ramp tool
• an update for the environment that should solve the problem of dependencies.

Updates have been tested locally and are working. Updating the environment requires recreating the environment locally.

Hi Margherita, interesting test workflow error that I have shared below. It indicates an error for the fiona package. I have locally tested it by assigning an arbitrary path and run the same code. The code runs without the attribute error.

Hi Emre!!! Then locally by updating the environment things work, I thought the changes were enough to change the CI-Linux enviroment as well, but that was not the case!
Yesterday @davide-f showed me how to modify CI-Linux, today I will try the modification and see if it works!

Theoretically I think the problem may be on the version of the Fiona package, after the Pypsa-Earth updates.
I will try, hopefully :D

@davide-f can you please check with this morning's change which environment is used by CI-Linux?

Few comments :) many thanks!
Indeed, the CI is not using the new env yet. With the proposed comment, it should work out

Great @Margherita-Capitani :D
