[Bug] Fix broken variables for database event (#17526)

Fix https://github.com/twentyhq/twenty/issues/17524

Recent update meant to support variable with spaces and dots broken the
database event variables. Inserting a variable `My Name` will be
inserted as `{{trigger.[My Name]}}`

For example, for a database event, we send `trigger.properties.after.id`
instead of `id`.
With the new code, we will consider `properties.after.id` as a variable
to wrap in `[]`, giving `trigger.[properties.after.id]` which cannot be
resolve.

Let's only support variable with spaces. Removing the logic to wrap
variable with dots.
