Fix `alacritty msg config` toml replacement

This fixes a regression introduced in bd49067 which broke the override
of configuration file variables using `alacritty msg config`.

To fix this the `replace` functionality was rewritten to behave more
like the `serde_utils::merge` where entire values are inserted into the
existing structure rather than separating the keys from the values.

Fixes: bd49067 (Switch to TOML configuration format)
