fix: restore commits for untyped section

[autumnjolitz]

Issue: #88
Resolves: #88

In versions prior to 2.4.1, Jinja templates could optionally generate change lines by accessing the "" section (e.g. untyped_section). This allowed for capturing of commit messages that would otherwise be lost.

Upon version 2.4.1, that was broken and untyped_section became always empty.

This PR restores the functionality.

Thank you for the PR @autumnjolitz! Could you add a test for this fix, so that we don't allow regressions to happen again 😊?

I do not understand your statement -- the ci/quality action returns:

src/git_changelog/commit.py:244:48: UP031 Use format specifiers instead of percent format
  src/git_changelog/commit.py:328:9: UP031 Use format specifiers instead of percent format
  src/git_changelog/commit.py:403:9: UP031 Use format specifiers instead of percent format

This PR -only- touches src/git_changelog/build.py while the complaint is regarding an entirely different file commit.py (from main as of yesterday afternoon)

Are you asking me to increase the scope of my PR to address an issue in a file I did not modify?

Please confirm if you wish me to handle that. I believe it is more likely a new version of ruff was released, was used in the github action, and is raising errors on previously "good" code.

Sorry for the confusion, I meant to add a test in the tests suite, to make sure that this behavior (the one that is now fixed thanks to your PR) stays the same in the future.

The tests suite is located in the tests folder. You can get inspiration from the existing tests to write a new one that asserts this behavior.

Let me know if this is unclear and I'll try to provide more guidance :)

Also, yes, please ignore the unrelated CI failure.

Test added as requested.

Perfect, thanks a lot!
