tsp-openapi3 - update query parameter transformations to support typespec 0.59 changes

[chrisradek]

Clear and concise description of the problem

@typespec/http v0.59.0 added uri template support. As part of these changes, the @query({format: }) option was deprecated in favor of setting #{explode: true} instead.

We should update the parameter transformation logic to no longer emit the deprecated version of the query decorator.
