There's a merged pull request on the void-packages repository

[RFC]: .github: improve the PR template
https://github.com/void-linux/void-packages/pull/33118

Description:
Filling out the "Does it run and build successfully" section is
necessary only when the CI is skipped, but this is easy to miss.
Separate it from the rest of the text to make it clearer.
