feat: add a tool that will allow Minerva create and send an `ics` file with the calendar events to the user

[yurijmikhalevich]

We can try experimenting with two approaches.

Option 1

Add a tool that lets Minerva respond with a file containing any text content. To use the tool, Minerva should call:

send_text_file(filename, content)

Pros: very flexible

Cons: increases the probability of it hallucinating incorrect info in the ics file (-:

Option 2

Add a tool that lets Minerva respond with a file containing events extracted from the real calendar (we should let it reference the events somehow).

I would start with Option 1 to see how it will perform.
