Backport bot failing with URISyntaxException

[jhoeller]

The backport bot got stuck after removing the label, never creating the actual backport issue for #27876:
https://github.com/spring-projects/spring-framework/actions/runs/6352096125/job/17255021867#step:5:373

In the meantime, I've manually created the backport issue.
It's still worth investigating why the bot failed there with an illegal character in the URI:
