Make it clear the /remind_me ToDo is a reminder
## Problem
When I set a reminder using `/remind_me`, here's an example ToDo I get once the time elapses:

It's not clear to me that this is a reminder, especially in this case since I had set it 8 days ago with [this comment](https://gitlab.com/gitlab-org/gitlab/-/issues/444459#note_1904238297).
Problem: I need to be able to tell apart which ToDos are reminders, and which ones aren't, since my typical use-case is for past-me to want future-me's immediate attention to the ToDo on that day/time. I have 15-20 ToDos open on a daily basis and need to tell the urgent ones apart.
This is exacerbated by the TODO linking to the general issue, instead of the comment that triggered the ToDo.
## Proposal
- Change the text to `You set yourself a reminder.`
- Link to original comment that used `/remind_me` (might be tricky because of comments with no text?)
