Refactor: Update neovim configuration

This commit refactors the neovim configuration to include several updates:

-   Added LSP support for Zig (`zls`).
-   Added `analyzer` and `zls` to `ale` linters.
-   Added `zigfmt` to `ale` fixers.
-   Added `towolf/vim-helm` as a plugin.
-   Added configuration for `lualine` to display Treesitter status.
-   Included SSH config from `conf.d/*.conf`.
-   Updated keymaps for LSP formatting.
-   Modified tabwidth and shiftwidth for rust files.
