chore: ensure that PR titles must be semantic (#1108)

<!-- markdownlint-disable MD041 -->
#### What this PR does / why we need it

This enforces Semantic Pull Request titles:
- see
https://github.com/amannn/action-semantic-pull-request?tab=readme-ov-file#examples
for examples
- see https://www.conventionalcommits.org/en/v1.0.0/#specification for
the full specification

We want this because we use squashing so all squashed commits should
conform to our commit style

#### Which issue(s) this PR fixes
<!--
Usage: `Fixes #<issue number>`, or `Fixes (paste link of issue)`.
-->
