LSP binary name

Taking a look at https://github.com/AineeJames/c3-zed/issues/1, it seems that there is an inconsistency in how extensions expect the LSP binary to be named. We currently have releases named as `c3lsp`, but the Zed extension expects `c3-lsp` and Nixpkgs exports `c3-lsp` as well, which I assume is due to the repository name. Should we change and standardize the binary name as `c3-lsp`? Perhaps we could provide both as separate zips for this release as a temporary workaround, and eventually transition into a single option (be it with or without the dash) after discussing with downstream.
