How can I specify the version for custom lua registry?

[fcying]

I have currently added a custom clangd using Lua. How can I specify the version of this LSP?

check version is nil:
clangd ■ new version available: nil -> 17.0.3

return Pkg.new({
    name = "clangd",
    desc = _.dedent([[
        custom clangd understands your C++ code and adds smart features to your editor: code completion, compile errors,
        go-to-definition and more.
    ]]),
    homepage = "https://clangd.llvm.org",
    languages = { Pkg.Lang.C, Pkg.Lang["C++"] },
    categories = { Pkg.Cat.LSP },
    ---@async
    install = function(ctx)
        local source
        local std = require("mason-core.managers.std")
        ctx.github_release_file = "https://github.com/fcying/tools/releases/download/tools/clangd_linux_amd64.txz"
        std.download_file(ctx.github_release_file, "clangd_linux_amd64.txz")
        std.untarxz("clangd_linux_amd64.txz")
        ctx.receipt:with_primary_source({
            type = "github_release_file",
            repo = "clangd/clangd",
            file = ctx.github_release_file,
        })
    end,
})

set primary_source with release = version can work
