Fix typo in ppa-automation workflow

[oskirby]

Description

In my last round of PPA automation hacking, I attempted to auto-generate the list of current Ubuntu distributions by fetching the distro-info-data repository and parsing the Ubuntu release data for EOL and release date.

Unfortunately, I left a typo in the file that led to a corrupted github outputs. Shame on me!

The workflow ends with an error message like the following:

Error: Unable to process file command 'output' successfully.
Error: Invalid format 'releasesfocal jammy noble oracular '
