Update the documentation of pasqal-cloud

[ShaheenPasqal]

Hello,
The documentation for Pasqal Cloud appears to be outdated, and some important definitions are missing or unclear.

Examples:

In the create_batch method of the SDK, certain arguments are not documented—specifically, device_typeandbackend_configuration`.

Additionally, some Python objects used in documented functions, such as DeviceType, EmulatorType, and JobFilters, are not described in the documentation.
