Subject: [PATCH] fix(lsp): vim.lsp.enable(...,false) does not disable  #32002

Problem:
Per the documentation, passing `false` as the `enable` parameter of
`vim.lsp.enable()` should disable the given LSP(s), but it does not work
due to a logic error.

Specifically, `enable == false and nil or {}` will always evaluate to
`{}` because `nil` is falsy.

Solution:
Correct the conditional statement.
