Fixes stray gap in Commit Graph header for published branches

The publish button host remained in the flex row even when it rendered
nothing (branch already has an upstream), and the parent's
`min-width: 3.1rem` icon-only floor forced the empty host to occupy
that width. Gate `gl-publish-button` in the parent so it's only in the
DOM when the branch has no upstream, mirroring the component's own
render guard.

 - Fixes pushing a branch that needs a force-push (e.g. after an amend or rebase) silently reporting success without updating the remote — a non-fast-forward (_tip of your current branch is behind_) rejection is now surfaced as an error instead of being swallowed as non-fatal ([#5364](https://github.com/gitkraken/vscode-gitlens/issues/5364))
 - Fixes _Fetch_, _Pull_, _Switch_, _Reset_, and _Restore_ operations silently reporting success when the underlying Git command failed with a message Git treats as a warning (e.g. an unreachable remote, or an invalid ref/revision) — these failures are now surfaced as errors instead of being swallowed as non-fatal
 - Fixes the working changes (WIP) stats tooltip in the details header duplicating the visible stats pill instead of describing the change breakdown — the tooltip now reads e.g. _1 file added, 2 files changed in the working tree_
+- Fixes a stray gap in the _Commit Graph_ header next to the fetch and sync actions when the current branch is already published — the publish action no longer reserves empty space once the branch has an upstream
