getAuthorizationSchemaValue
Generates the value of the Authorization header based on the provided scheme requirements.
If an HTTP scheme is present, uses the configured value or a placeholder for that scheme.
Otherwise, builds a deterministic placeholder from OAuth2/OpenID Connect schemes, sorted by scheme name and rendered as
<scheme:[scope1,scope2]>.
Return
authorization header value to use in a valid test case
Parameters
authorizeHeaderRequirements
list of security scheme requirements and scopes
Throws
if the provided list of requirements is empty
