When an issue is reopened, the action is 'reopen', but the state is 'opened' (as
we don't have a separate 'reopened' state any more).
Because we checked the action in one method and the state in another, this lead
to a weird case where the mesage neither linked to the issue, nor contained an
attachment with its details. Just checking the action is fine, as it's the most
granular.
We used to include the first and last name of the user, but !6624 modified
this to include only the username. Let's compromise and add both in the form
of `First Last (username)`.
Closes#38865
In the pipeline message, the duration of the pipeline was shown as:
> gitlab-org/gitlab-ee: Pipeline #8002259 of master branch by Douwe Maan
failed in 8612 seconds
But this many seconds only gave me a clue how long the pipeline took,
so now this will be shown as something like: 02:20:12 which gives a much
better measure of time.
