Fixes similarity threshold ignored in diff file listing

`getDiffStatus` used a bare `-M` for rename detection, falling back to Git's
default 50% threshold instead of the configured `gitlens.advanced.similarityThreshold`.
The same value is correctly wired in `getDiffForFileCore`; this restores the
`context.config.commits.similarityThreshold` fallback here too. Regression from
the standalone-packages refactor.

 ### Fixed
 
 - Fixes opening the _Commit Graph_ in multi root workspace to the correct repo ([#5276](https://github.com/gitkraken/vscode-gitlens/issues/5276))
+- Fixes the `gitlens.advanced.similarityThreshold` setting being ignored when listing changed files for a diff — rename detection used Git's default threshold (50%) instead of the configured value
 - Fixes force push from the _Push_ command always using `--force-with-lease` (and `--force-if-includes`) and ignoring VS Code's `git.useForcePushWithLease` and `git.useForcePushIfIncludes` settings — the confirmation could offer a plain `--force` while GitLens still pushed with lease; it now honors the configured preference
 - Fixes _Stash Unstaged Changes_ also stashing staged changes when an untracked file is involved — including untracked files no longer drops the `--keep-index` flag, so staged changes are correctly kept intact ([#5281](https://github.com/gitkraken/vscode-gitlens/issues/5281))
 - Fixes push from the _Commit Graph_ silently pushing to a wrong remote branch when the local branch tracks a differently-named upstream (e.g., `feature/foo` tracking `origin/main`) — now correctly pushes to the configured upstream branch instead of creating a new remote branch ([#5304](https://github.com/gitkraken/vscode-gitlens/issues/5304))
