Describe the bug

PS C:\Users\caperal\repos\azure-rest-api-specs\specification\storage\Microsoft.BlobStorage> tsp compile .                 
TypeSpec compiler v0.64.0

Diagnostics were reported during compilation:

Found 20 warnings.

Since warnings are shown as errors in ci in the specs repo, this will block merging the PR. Spoke to @timotheeguerin who suggested the error might need to be moved in order to be able to suppress it in the spec.

I think for this specific error it should be emitted on teh parameter instead which would solve this specific case.

But more genericaly we have to decide how we can suppress those errors.
