fix(vertico): 9 workspace limit in switch-workspace-buffer

+vertico/switch-workspace-buffer was hardcoded to only list buffers from
the first 9 workspaces. This removes that limit.

Minor catch: workspaces beyond 9 will use lower case a-z as narrowing
keys, followed by upper case A-Z. There will not be any valid narrowing
keys beyond 61 workspaces -- but who in the world would have that many?
