Fix Eventhubs vcpkg manifest

[antkmsft]

Vcpkg CI currently fails: microsoft/vcpkg#17119

Overall looks good, but we need to find why we are depending on storage and remove that.

If that's outside the scope of this PR and requires more work to address, let me know, and I can file an issue instead.

Per offline discussion, this is working as intended for how EventHubs works, and hence a separate issue.

I was wondering what the failures/errors were in vcpkg.

One of them seems to be this:
https://dev.azure.com/vcpkg/public/_build/results?buildId=91832&view=logs&j=878666d5-db33-5b27-9e7d-b0c7ee352005&t=9a0acc60-e136-51ce-90f9-d151828126f7

C:\a\1\s\ports\azure-messaging-eventhubs-cpp\vcpkg.json:17:36: error: Trailing comma in an object
on expression: "name": "azure-core-amqp-cpp",

I am not sure how we are fixing that here.

The other issue is:

@ahsonkhan, please re-review in the light of the fact that the dependency is correct.
