[Security Solution] Remove exceptions_list, author and license …

…from Diffable Rule (#196561)

Resolves: #196213

## Summary

Excludes the fields `exceptions_list`, `author` and `license` from the
`DiffableRule` definition.

This will:

- prevent them from appearing in the Three Way Diff component
- prevent them from being able to be passed as a value in the `fields`
object of the `/upgrade/_perform` endpoint to set a specific
`pick_version` for it (NOTE: the current logic already forces
`exceptions_list` to upgrade to the CURRENT version, but removing it
from DiffableRule, will completely remove the from the payload schema,
and the endpoint will then throw a validation error if included, rather
than silently ignoring it)
