Created doc for “how to verify and how to do release” (release doc) (WIP) This documents/should document: * what the signatures are and what they proof * how to verify them * how to build releases (I know more of a maintainer doc, but yeah, I found it a good place here, if you want a separate one feel free) This should also make it easier for other maintainers to create releases or so. @elrido feel free to adjust/push to the branch if you want to have some details fixed. I have left some TODOs of stuff where I am unsure.

# Release
updated release document - removed duplicate content - clarified what is signed and since which release - updated verification sample output (also in wiki) using the output of https://github.com/PrivateBin/docker-nginx-fpm-alpine/actions/runs/7228527399/job/19698112056#step:7:156 - Corrected release process - we trigger the release on the push of the tag, not a branch (fixed point in time instead of a moving target)

As of the PrivateBin 1.0 release we [cryptographically sign](https://git-scm.com/book/uz/v2/Git-Tools-Signing-Your-Work) our git commits and tags, so that you can verify we actually developed the software. Later, we also [started signing the release archives on GitHub](https://github.com/PrivateBin/PrivateBin/issues/219) and retroactively signed all releases from 1.0 forward.

Since [release 1.6.2](https://github.com/PrivateBin/PrivateBin/releases/tag/1.6.2) our release assets additionally also are [verified with the SLSA (Supply-chain Levels for Software Artifacts) framework](https://slsa.dev/), providing an in-toto manifest of the release archive.

This achieves the following:
1. It ensures no maintainer has gone rogue and has modified/tampered with the source code before “building” the release.
2. It ensures the release is build exactly according to the source as defined by the branch that was used for the release.
This includes the workflow file defining how the release is done itself.
3. Our release should achieve [SLSA build level 3](https://slsa.dev/spec/v1.0/levels#build-l3) as it [runs on GitHub](https://slsa.dev/spec/v1.0/threats). Some more properties [are thus achieved](https://slsa.dev/spec/v1.0/threats).
For more information [see the corresponding issue](https://github.com/PrivateBin/PrivateBin/issues/1169) and [the GitHub workflow file](/.github/workflows/release.yml).

All releases `.tar.gz` and `.zip` archives since 1.0 come with corresponding `.asc` signatures that can be used to confirm the authenticity of the fact that the release has been issued by a PrivateBin maintainer.

This uses traditional [PGP](https://en.wikipedia.org/wiki/Pretty_Good_Privacy) signatures.

## Verification
You can use the gpg signatures for verifying the reproducibility and that a maintainer in posession with that PGP private key created the release with that content:

The release process is outlined in the [release checklist](https://github.com/PrivateBin/PrivateBin/wiki/Release-Checklist). The key manual steps are performed using a [Makefile](https://github.com/PrivateBin/PrivateBin/blob/master/Makefile#L31-L43) and using a [shell script](https://github.com/rugk/gittools/blob/master/signrelease.sh).
