Change get porcov version

[MarieLataretu]

Hi there,
it's me again, again with the same line and I can't explain why and how.

With Nextflow 24.10.4, I get, sometimes, not always, a json/text returned that has spaces between the key-value pairs. This leads to an index out of bounds error, because the splitting does not work as expected.

Excerpt from 'https://api.github.com/repos/replikation/poreCov/releases/latest'.toURL().text:

<...>
  "tag_name": "1.12.2", <--- ":<space>"
  "target_commitish": "master",
<...>

Anyhow, I changed the Groovy function to get the latest release.

I hope this solves the issue on my side, and works for anyone else, too.
