chore: Improve tag fetching in create-update-issues workflow (#5299)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so

your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?

This PR modifies how tags are fetched in the create-update-issues
workflow by replacing the `fetch-tags` input parameter with an explicit
`git fetch` command.

- Removed `fetch-tags: true` from checkout action
- Added separate step to fetch tags using `git fetch --prune --unshallow
--tags`

This change provides more explicit control over tag fetching and ensures
we get a complete tag history with pruning of stale refs.
