Deprecated validation endpoint

[kilianus777]

Describe the bug

The memory chart references and creates a validation endpoint and service.
Afaik this endpoint is not available anymore and results in a 404 error during token validation.

To Reproduce

1. Deploy the default edc memory chart two times
2. Try a data transfer between the two EDCs
3. Fails with 404 by the token transfer endpoint

Expected behavior

The template of the "normal" chart uses the CONTROL_PATH and CONTROL_PORT instead.
After manually changing the EDC_DATAPLANE_TOKEN_VALIDATION_ENDPOINT to the control endpoint, the transfer succeeds.

Context Information

• Used version: chart 0.5.3

Possible Implementation

I guess the fix would be to use the same template as in the "normal" chart.
But I wanted to confirm, before I create a PR.

Hey @ndr-brt, is it possible to reopen the PR or should I consider this as rejected?

[ndr-brt]

re-opened it, it just fell off ignored. I will add reviewers so that won't happen again
