* Move top level lsp config to editor.lsp This is mainly done to accomodate the new lsp.signature-help config option that will be introduced in https://github.com/helix-editor/helix/pull/1755 which will have to be accessed by commands. The top level config struct is split and moved to different places, making the relocation necessary * Revert rebase slipup
