feat: add Operate and Tasklist issues/sections

[houssain-barouni]

Add Tasklist and Operate sections in the changelog with respective Tasklist and Operate issues labeled with component/tasklist and component/operate

[Zelldon]

I was wondering whether we maybe should fork this repo and create it in the camunda org, and then adjust it to our needs. As right now it is intended to work with Zeebe and also their patch releases, but we want to get it work with the mono-repo and soon called Camunda application. For me it might make sense to have a cleaner cut here. Wdyt?

@npepinpe @romansmirnov any opinion?

I would prefer not having to build such a tool in the first place, especially if we're migrating all teams to it 🤔

[Zelldon]

What would be the alternative :D I guess generating changelog by Github? But somewhere you need some glue code to make it "pretty" and adjust it to your needs. Either with configuration and using some tools/actions or simply doing like done with zcl 🤷🏼

Hi @npepinpe, can we have this merged if it is ok ? That will help generating Tasklist and Operate release notes that is missing today in the mono-repo.

[npepinpe]

Looks fine, note that I did not test it, I assume you already did :)

I still maintain we should drop this tool 😄

I tested with the following

export ZCL_FROM_REV=8.6.0-alpha1
export ZCL_TARGET_REV=8.6.0-alpha2

I tested first adding the version: 8.6.0-alpha2 label to the issues

  zcl add-labels \
    --token=$GITHUB_TOKEN \
    --from=$ZCL_FROM_REV \
    --target=$ZCL_TARGET_REV \
    --label="version:$ZCL_TARGET_REV" \
    --org camunda --repo zeebe

but got fatal: bad revision '8.6.0-alpha1..8.6.0-alpha2', I think it is due to that 8.6.0-alpha1 tag does not belong to any branch as release-8.6.0-alpha1 was deleted without merging to main

Then tested the generation of ChangeLog with the existing labeled issues

  ./bin/zcl generate \
     --token=$GITHUB_TOKEN \
     --label="version:$ZCL_TARGET_REV" \
     --org camunda --repo camunda

and it is working including Tasklist and Operate sections
