    Fix #272: also use signature label offsets for parameter info
    
    According to the LSP specification, a parameter of a callable-signature
    has a label and a optional doc-commet. The label of a parameter
    information is either a string or an inclusive start and exclusive end
    offsets within its containing signature label.
    
    Previously, this was only taken in account for highlighting the
    parameter in the definition signature.
    
    * eglot.el (eglot--sig-info): Handle signature label offsets
      when printing the signature parameter information.
