Subject: [PATCH] Trim trailing space from discovered Python versions.

The setup-python action failed because my .python-version (generated from a recent pyenv) had a trailing newline (not sure if this is a bug in pyenv, but I'll look there next).

```
Installed versions
  Version 3.11.3
   was not found in the local cache
  Error: The version '3.11.3
  ' with architecture 'x64' was not found for Ubuntu 18.04.
  The list of all available versions can be found here: https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json
```

As you can see, the version was not discovered because the newline didn't match exactly. The way I figure, even if this is user error, stripping trailing space is super easy, and will probably prevent some problems.
