Changes at "Initiatives notifications enhancement"

Is your feature request related to a problem? Please describe.

As a user creating an initiative, I expect to receive several notifications to follow up on my initiatives updates (same for the followers).

Describe the solution you'd like

Create initiative notifications for the following events:

• the initiative has received an answer
• the initiative has reached the end of the signature collection period

IMO, both of those notifications should be sent to administrators, authors and initiatives followers.

Describe alternatives you've considered

None

Does this issue could impact on users private data?

No

Funded by

CESE

Additional info

I withdrew this proposal, which was a bit confusing: gid://metadecidim/Decidim::Proposals::Proposal/15122 and replaced it by this one, more simple.
