docs / edge functions

[TizianoT]

Considering the following issues related to edge functions

• Missing Documentation of REST API Details for Edge Functions #88
• HTTP PUT - Endpoint Not Found sdk#30
• https://github.com/orgs/sqlitecloud/discussions/38
• https://github.com/orgs/sqlitecloud/discussions/37
• HTTP PATCH - Unauthorized Error sdk#29

It is important to clarify the methods used to run edge functions. These are POST and GET based on whether the user wants to provide a body.

Talking about the other methods:

• PATCH is used to create or update an edge function
• DELETE is used to remove an edge function
• PUT doesn't exist

So the edge functions page of the documentation has to be improved to clarify that the method used to call an edge function is not related to what the edge function does.

E.g. an edge function that removes items from a database is called with a POST or with a GET request.
