fish-lsp: prevent bot bumps on pre-releases

  # fish-lsp adds tags for all its pre-release versions, which leads to

  # incorrect r-ryantm bumps. This regex allows a dash at the end followed by a

  # number (like `v1.0.9-1`). but it prevents matches with a dash followed by

  # text (like `v1.0.11-pre.10`). or, of course, no dash at all
