wip: uipath-platform

[radu-mocanu]

• extract platform in a segregated library
• refactor changes from this PR, decoupling the cli from the platform -> pass extra arguments only to the llm service, not to the entire UiPath object

Depends on:
https://github.com/UiPath/uipath-platform-python/pull/2

❗ToDo before merging:

• remove dev versions
