Subject: [PATCH] Fix string escaping in flake.nix regex

`\.` in a Nix string is interpreted as an invalid escape sequence,
which currently ignores the backslash and evaluates simply to `.`.

This is not the desired behavior, and also a deprecated features of Nix.
The recent release of Lix 2.95 introduced a warning for these cases.
