chore(deps): bump dulwich from 1.2.3 to 1.2.4

[dependabot]

Bumps dulwich from 1.2.3 to 1.2.4.

Release notes

Sourced from dulwich's releases.

dulwich-1.2.4

Tolerate ref names with empty path components (e.g. `refs/tags//v1.0`) for now, emitting a `DeprecationWarning` rather than raising a `RefFormatError`. Such names are constructed by older Poetry releases (fixed in Poetry 2.4.0) and were silently accepted before Dulwich 1.2.3. `local_branch_name`, `local_tag_name` and `local_replace_name` likewise warn about, and strip, a leading slash instead of raising `ValueError`. Both will become errors again in a future release. (Jelmer Vernooij, #2192)
