Fix: Sync project/group resource access token webhook events to match current documentation

[vntw]

Update: After raising this issue, this merge request updated the webhook payloads that we can expect.

This PR updates the payloads and structs to reflect that ✌️

I searched for other places in the code where a format like 2024-01-24 16:27:40 UTC occurs and found (among others) this which I used as a reference:

go-gitlab/event_webhook_types.go

Lines 832 to 833 in 2c4b565

	CreatedAt string `json:"created_at"`
	FinishedAt string `json:"finished_at"`

Hope that this is the correct way! Let me know if it's not

Hmm... Yeah the inconsistencies around how time is used in the API is quite frustrating. In this case I guess it would make sense to first open an issue with GitLab to see if it's a bug there which they need to fix instead?

Good idea, I'll create an issue (if there hasn't been one already) and report back

e/ issue created

Thanks again for the hint, turns out there was more to it 😃 I updated the PR with the necessary links and info.

I think this is ready now!

It's a shame the used time formats are such a mess. We could introduce a UTCTime struct like the ISOTime struct to enable parsing it as a time.Time, but for now I'm not going to bother and it could be an annoying change to existing users of the API.

So thanks for your efforts 👍🏻
