fix(CI): Fetch all history

[lslezak]

Problem

• The packages in the Staging project have RPM versions like 1717740471.88237f7b, e.g. Unix time stamp + short commit SHA
• It should be something like 8+192, i.e. the latest version tag + number of commits since then
• The problem is that the cloned Git repository in CI does not contain any tags

Solution

• We need to find the latest version tag in the history. By default the action/checkout uses "--depth 1" parameter which fetches only a single commit without history. I guess this problem was introduces by upgrading actions/checkout to version 4.
• The fix is to checkout the complete history

Notes

• I found a solution which allows to fetch history only up to a specified tag, this decreases the amount of data to download as it does not fetch the complete history.
• However, finding the latest tag on the server and the downloading the content using several commands has a big overhead. Currently downloading the whole history is faster than this optimized process. It would make sense only on a really slow internet connection. With any decent connection the full clone is faster.
• But I guess that at some point in the future, when the Git history grows a lot, this approach will be faster and more efficient

@lslezak Arguably this is a bug in the github action or its documentation, fetch-tags is ineffective alone.
