Bumps fluxcd/pkg/git to v0.52.0, which exposes the generic
signature.Signer interface and the NewOpenPGPSigner / NewSSHSigner
constructors, and migrates pkg/bootstrap's two WithSigner call sites
accordingly. Refs fluxcd/pkg#398[1].
Adds a parallel WithSSHCommitSigning option alongside the existing
WithGitCommitSigning so callers can sign commits with an SSH private
key. PlainGitBootstrapper now dispatches through a new resolveSigner
helper that returns either an OpenPGP or SSH signer; the
repository.WithSigner option is appended conditionally to avoid the
typed-nil interface hazard the new generic field introduces.
The bootstrap path's OpenPGP entity selector is renamed and exported
as SelectOpenPGPSigningEntity so the flux CLI's pre-flight (introduced
later in this branch) can call it directly instead of carrying a
duplicate.
