fix(util.lsp): LazyVim.lsp.execute only request single client (#6904)

## Description
`LazyVim.lsp.execute` uses `vim.lsp.buf_request` which sends the request
to all attached clients.

`LazyVim.lsp.execute` seems to me to be the equivalent of
[vim.lsp.buf.execute_command](922816877f/runtime/lua/vim/lsp/buf.lua (L1366-L1376)),
but adds the option to also open in Trouble. Otherwise the request is
being made the same way. This command will be deprecated in 0.12 and
it's advised to use `client:exec_cmd` instead.

Since LazyVim supports Neovim >=0.11.2, it makes sense to refactor the
corresponding codeblock and use `client:cmd_exec` instead (it's already
available in Neovim 0.11).

I only changed the necessary parts where `vim.lsp.buf_request` was being
used and not Trouble (when `opts.open = true`), since I'm not familiar
with its codebase. That's also why I went for extending `params` in the
`else` branch instead of adding `title` into original `params`, since I
didn't know how Trouble will react to this change. Not sure if maybe
there also needs to be some change there.
