[Request] Use GoReleaser for publishing

cc #5

pacaptr has been using hand-written GitHub Actions workflows for publishing since the very beginning.

However, in the long run, I would like to reduce the mental overhead of maintaining pacaptr by delegating the publishing workflow to the wonderful GoReleaser project.

I have been getting more familiar with GoReleaser by trying it on my other projects like Claveilleur, ting and Ouverture. When the time comes, I'll migrate pacaptr to GoReleaser.

At the same time, I would like to express my gratitude to all the collaborators working on package distribution, notably:

• @lynzrand for working on the original choco workflow;
• @amiarobot for adding debian packaging support;
• @meltinglava and @ptanmay143 for distributing pacaptr on scoop.
