Comments on the Issue (you are @copilot in this section)

@max-wittig Inside the web container. We're doing something like this. I think its enough to create the requirements.txt file as far as I know

requirements.txt

sentry-auth-oidc==9.0.0 \
    --hash=sha256:14ba07eb49520a18dd91909493af928c875c405178594b44aae2e37b5d579320

Dockerfile

FROM getsentry/sentry:{{ sentry_version }}

COPY . /usr/src/sentry

RUN if [ -s /usr/src/sentry/enhance-image.sh ]; then \
    /usr/src/sentry/enhance-image.sh; \
fi

enhance-image.sh

#!/bin/bash

set -e

apt-get update
apt-get install --no-install-recommends -y git

if [ -s /usr/src/sentry/requirements.txt ]; then
    pip install -U -r /usr/src/sentry/requirements.txt
fi

git apply /usr/src/sentry/*.patch
```</body></comment_new>

Fixed the commitlint failure by adding a commit with proper conventional commit format. The previous commits didn't follow the required type: subject format. Commit 6bbf76b
