[IDEA]: Add variables in the changelog, so that it becomes easier to manage it in each release

[matbmoser]

Description

There is a cool feature from markdowns that is the "variables":

[VARIABLE]: content

When inserting it, you need to do this:

[VARIABLE]

Proposal

I would change all the urls from the changelog to a more easier structure:

<!-- START This part will not be visible --> 

<!--  Global Definitions  -->
[tx-repo]: https://github.com/eclipse-tractusx
[tag-prefix]: /releases/tag

<!-- Products  -->

<!-- IRS -->
[irs]: item-relationship-service
[irs-release-url]: [tx-repo][irs][tag-prefix]

<!-- DPP -->
[dpp]: digital-product-pass
[dpp-release-url]: [tx-repo][dpp][tag-prefix]

<!--END This part will not be visible --> 

## R24.08

<!-- START This part will not be visible --> 

<!-- IRS -->
[IRS-APP-R2408]: 7.1.3
[IRS-HELM-R2408]: item-relatinship-service-7.1.3

<!-- DPP -->
[DPP-APP-R2408]: v4.0.1
[DPP-HELM-R2408]: digital-product-pass-4.0.1 

<!--END This part will not be visible -->

Acceptance Criteria

• [ ] Variables are working as expected
• [ ] Complexity is reduced

Examples:

In my repository I used some variables to define the urls in the footer:

https://github.com/eclipse-tractusx/digital-product-pass/blob/2ecd19b34b4f587101c0c2c8e5f7e3727ada6286/README.md?plain=1#L159-L168

Things to consider here:

• apps sometimes do versioning with v prefix and sometimes not - can be handled with this approach
• KIT routes are inconsistent. See this issue - cleanup together makes sense

[matbmoser]

Good points!

In this way every product/kit could define their version with and without 'v'. You can see with the IRS and the DPP:

That makes it easier.

And yes sure, for kit the location should be standardized at least for the "changelog"

Lets talk about this in the committer meeting.
