chore: ensure the Helm Chart release process can release new versions of kratix-destinations

[SaphMB]

Given I have updated the kratix-destinations helm chart
When I push the code changes
Then a Github action should trigger a new release of the kratix-destinations helm chart

Following the recent updates to the release process for the Helm Chart, the release process no longer uses the helm chart release Github Action which, without intervention, would bump and release any charts within the repo. It currently only releases the versions of the kratix chart. Should any aupdate be made to the kratix-destinations chart, it should release new versions of this chart too.
