Update lsp-mode recipe in MELPA to include lsp-roslyn-stdpipe.ps1

[kiennq]

Thank you for the bug report

• I am using the latest version of lsp-mode related packages.
• I checked FAQ and Troubleshooting sections
• You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

With #4279, lsp-roslyn-stdpipe.ps1 needs to be included in the package distribution.
We should update the melpa recipe to reflect that.

Probably something like

(lsp-mode :repo "emacs-lsp/lsp-mode"
          :fetcher github
          :files (:defaults
                  "clients/*.*"))
