Add communication about start and end-date of role to invite mail.

[MarliesRikken]

New Feature Request

Summary

Regel toevoegen aan invite mail met start - eind datum van rol. Overwegen of we dit willen.

Problem: What is the pain point? (e.g., "Users cannot filter results by date.")
Invite mail bevat nu geen informatie over start/eind datum. Gebruiker heeft de informatie nu niet.

Value: Why should we build this? (e.g., "Improves data accessibility for
power users.")
Verzoek van instelling. Gebruiker in meer detail informeren over zijn/haar toegangsrecht.
