Workflows: Fix "Stable tag:" reamde.txt field in SVN upload (#31897)

Our SVN plugin upload workflow currently clears the `Stable tag:` field in `readme.txt` when preparing the plugin for upload to SVN. This commit fixes the issue by using `awk` rather than `grep` + a RegEx. Another advantage of the new solution is that it can be easily tested on a non-bash shell (e.g. on macOS).
