commit 1e6ed5441a61b5085978e0429691e2e2425f6846 ("notes: rename to
load_display_notes()").

Update to git version v2.24.0.

Never use get_cached_commit_buffer() directly, use repo_get_commit_buffer()
instead. The latter calls the former anyway. This fixes segmentation fault
when commit-graph is enabled and get_cached_commit_buffer() does not return
the expected result.

Update to git version v2.22.0.

Upstream commit bce9db6d ("trace2: use system/global config for default
trace2 settings") caused a regression. We have to unset HOME and
XDG_CONFIG_HOME before early loading of config from trace2 code kicks in.
