Reproduction steps

$ cd SomeGitRepo  # a repo where there are signed commits
$ git config --local log.showSignature true
$ git log  # check that there are signed commits
$ zed -n .

Then:

• open file history for a file
• notice the commit hashes are replaced by signatures
• try to click on a commit to show the diff, it won't work
• open git graph
• click on a commit, it will show 0 changed files
• double-click on a commit
• click on the "Commit SHA" copy button
• paste somewhere---it's wrong

Current vs. Expected behavior

Current behavior:

1. In the file history view, the signature replaces the commit hash

2. In the file history view, clicking on the commit does not jump to a diff of the commit

3. In the git graph view, the commit pane erroneously shows 0 changed files

4. In the git graph view, double clicking on the commit leads a to a single-commit visualization with missing diff and where the "Commit SHA" copy button copies the signature to the pasteboard

Expected behavior:

1. File history shows commit hashes

2. Clicking on a commit in file history leads to a single-commit visualization

3. In the git graph view, clicking on a commit shows a pane with the count of changed files

4. In the git graph view, double-clicking on a commit leads to a single-commit visualization with a diff and correct hash copy button
