fix: completion.enable(false,...) deletes invalid augroup #32121

Problem:

    vim.lsp.completion.enable(true, client.id, bufnr)
    vim.lsp.completion.enable(false, client.id, bufnr)

    Error detected while processing LspDetach Autocommands for "*":
    Error executing lua callback: …/lsp/completion.lua:701: Vim:E367: No such group: "vim/lsp/completion-22"
    stack traceback:
            [C]: in function 'nvim_del_augroup_by_name'
            …/lsp/completion.lua:701: in function 'disable_completions'
            …/lsp/completion.lua:724: in function 'enable'

Solution:
Delete the correct augroup.
