update github actions version comments to use full version names

for example

```diff
- uses: actions/setup-java@ad2b38190b15e4d6bdf0c97fb4fca8412226d287 # v5
+ uses: actions/setup-java@ad2b38190b15e4d6bdf0c97fb4fca8412226d287 # v5.3.0
```

(https://github.com/cigaleapp/cigale/pull/1809)

cuz the updates are not really readable otherwise

see how we can do it in the docs, if we cant find ask on the discussions of the renovate repo
