Avante was removed in c26b6c9 but blink-cmp-avante stayed as a dependency and
"avante" stayed first in sources.default, so the provider still loaded at
startup. Restore `keymap = { preset = "super-tab" }` now that LazyVim#6183 has
shipped; the workaround called require() during spec evaluation, which pulled
blink.cmp into startup.
