git: Degrade gracefully when refreshing git state (#57292)

This PR changes the git store's `compute_snapshot`, which runs to update
state that depends on the contents of `.git`, to degrade gracefully when
fetching individual pieces of state fails. For example, when fetching
the list of branches fails, instead of returning early from the function
(leaving the previous git state snapshot in place with stale state), we
continue with an empty list of branches. This prevents failures of
individual git commands from making the entire git UI get stuck
indefinitely.

Closes #ISSUE

Release Notes:

- Fixed an issue where failing to fetch branches using the git CLI would
prevent other git-related state from being updated.
