Prepare v3.8.0-rc.1

For "release note", see: #1266

This does not bump the version.Version variable, as this is already done by the build process and this release itself is a release candidate. When the --version flag in an existing sops binary would already make use of the GitHub API, it would not report it as "latest" either.

Fix formatting. The file format is RST, not MarkDown, so double backticks are needed instead of single ones.

Also, don't you need to update version/version.go?

I've created #1269 to fix similar issues in the remainder of the file. Turns out nobody ever used proper RST in it for code formatting... (I guess we could also rename this to CHANGELOG.md instead, though I have no idea whether the file is linked from somewhere. In the repo it seems to be only referenced in docs/release.md.)

See bit in pull request description around not bumping the version.Version variable.

I'm sure one day we can pivot to making this file md but for now it's probably good to keep it rst

Yeah, reading helps :) Sorry for the noise.

Tiny part of the SLSA provenance attestation failed due to an apparent GitHub Actions outage. But the release is out! 🎉

Figured out the reason for the failure. As this is a (relatively) new GitHub organization, I forgot to enable the settings which allows a package (container image) to be publicly available. This has been addressed now.
