fix(release): remove GNUism

[multani]

grep -p is GNU specific and doesn't work on MacOS

On MacOS, the following steps are not working due to the -P option used in the grep command:

make .release.generate-notes
make .release.bump-chart-version

[Copilot]

Pull request overview

Updates release helper scripts to avoid GNU-specific grep -P/-o usage (which breaks on macOS) by switching YAML field extraction to yq.

Changes:

• Replace grep -Po parsing of Chart.yaml fields with yq lookups in release note generation and version bump scripts.
• Minor formatting/no-op change in download-chart-docker-images.sh.

Reviewed changes

Copilot reviewed 2 out of 3 changed files in this pull request and generated 3 comments.

File	Description
scripts/generate-release-notes.sh	Use yq to read chart name and version instead of GNU grep -P.
scripts/bump-chart-version.sh	Use yq to read chart version instead of GNU grep -P.
scripts/download-chart-docker-images.sh	Formatting-only change (no functional impact).

LGTM 👍 , I guess we might need to manually verify this? on both macos and linux 😄

Can you run:

make .release.generate-notes .release.bump-chart-version

It should modify local files and that should work with MacOS now

@pranjalg13 can you run this on mac?

I rebased with main, still getting this error:

It is not bumping the version automatically

It is not bumping the version automatically

Actually, it also doesn't work on main at the moment 🤦

@pranjalg13 can you try again from the latest version of this branch with:

make .release.bump-chart-version .release.generate-notes

(I changed the order of the make targets above ⬆️, to bump first, then generate the release notes)

[ChrisKujawa]

I think the problem with this is that we need yq installed 🤔 Not sure whether we can expect this to be the default. Do we have configured/documented as requirement?

[multani]

yq is already used in other scripts and installed by the Docker builder too.

I guess it's reasonable to assume releaser would have yq already installed.

make .release.bump-chart-version .release.generate-notes

(I changed the order of the make targets above ⬆️, to bump first, then generate the release notes)

I earlier tried that as well but this was the error:

pranjal.goyal@Pranjals-MacBook-Pro camunda-load-tests-helm % make .release.bump-chart-version .release.generate-notes
sed: 1: "charts/camunda-load-tes ...": command c expects \ followed by text
make: *** [.release.bump-chart-version] Error 1

I guess it is fine, not a big issue 😄 , I will use GitHub action
