ci: fix cron job for auto tagging

[florianl]

Fix the trigger for the auto tagging job. At the moment it would run on every day of January instead of every 1st of each month.

Here is the format:

┌───────────── minute (0 - 59)
│ ┌───────────── hour (0 - 23)
│ │ ┌───────────── day of the month (1 - 31)
│ │ │ ┌───────────── month (1 - 12 or JAN-DEC)
│ │ │ │ ┌───────────── day of the week (0 - 6 or SUN-SAT)
│ │ │ │ │
* * * * *

Changed the schedule from the 1st of the month to 3rd of the month, as I hope this fix gets approved and merged, before this possible next schedule and we see it in action.
And as we are supposed to provide a tagged version for OTel collector release, tagging should happen rather soonish.

How about adding a workflow_dispatch to the job so we can run it manually if needed?

How about adding a workflow_dispatch [..]

I was looking into this, but couldn't find a proper way to limit it to a user group. Ideally only maintainers (or approvers) of the project should be able to trigger a workflow_dispatch run to tag a new version. As I didn't find anything around authorization for this kind of trigger, I did not add it.

Only folks with write permissions should be able to trigger a workflow.

Only folks with write permissions should be able to trigger a workflow.

I wasn't aware of that and obviously didn't find any documentation around it. Added the manual trigger with 08dfef9.

From the doc above:

Write access to the repository is required to perform these steps.

Thanks @christos68k for merging.
While I don't have permissions to merge PRs, I seem to have permissions to trigger workflows:
