A vararg splice must be the only argument for a repeated parameter.

Fixes #11419

Build failure in scaladoc/compile:

 Error:  -- Error: /__w/dotty/dotty/scaladoc/src/dotty/tools/scaladoc/renderers/MemberRenderer.scala:89:6 
Error:  89 |      m.docs.map(_.deprecated.toSeq.map(renderDocPart)):_*
Error:     |      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error:     |Sequence argument type annotation `*` cannot be used here:
Error:     |it is not the only argument to be passed to the corresponding repeated parameter A*

Looks like that code needs to be fixed to do a Seq(..) ++ foo instead of Seq(.., foo: _*)
