pass: stop installing password-store.el

password-store.el is on MELPA so it is available in Nixpkgs as
emacs.pkgs.password-store.

Using emacs.pkgs.password-store is preferred because of better package
quality:
- Emacs lisp package dependencies are automatically installed
- byte-compilation is done
- native-compilation is done

+- `pass` now does not contain `password-store.el`.  Users should get `password-store.el` from Emacs lisp package set `emacs.pkgs.password-store`.

 - `mariadb` now defaults to `mariadb_1011` instead of `mariadb_106`, meaning the default version was upgraded from 10.6.x to 10.11.x. See the [upgrade notes](https://mariadb.com/kb/en/upgrading-from-mariadb-10-6-to-mariadb-10-11/) for potential issues.
 
 - `getent` has been moved from `glibc`'s `bin` output to its own dedicated output, reducing closure size for many dependents. Dependents using the `getent` alias should not be affected; others should move from using `glibc.bin` or `getBin glibc` to `getent` (which also improves compatibility with non-glibc platforms).
