fish: use babelfish for hm-session-vars.sh (#4012)
* home-environment: add `home.sessionVariablesPackage`

Allow the `hm-session-vars.sh` derivation to be referenced from other
modules, e.g. to translate it to fish with babelfish at build time.

* fish: use babelfish for `hm-session-vars.sh`

Translate `hm-session-vars.sh` to fish at system build time,
significantly decreasing shell startup time.

== Release 23.05
The 23.05 release branch became the stable branch in May, 2023.
[[sec-release-23.05-highlights]]
=== Highlights
This release has the following notable changes:
* Firefox add-ons are now managed per-profile.
That is, if you are currently having
+
[source,nix]
programs.firefox.extensions = [ foo bar ];
+
in your configuration then you must change it to
+
[source,nix]
programs.firefox.profiles.myprofile.extensions = [ foo bar ];
* The default configuration location has been changed from
`~/.config/nixpkgs/home.nix` to `~/.config/home-manager/home.nix`.
+
Similarly, if you are using a Nix flake based setup
then the default flake file location has changed from
`~/.config/nixpkgs/flake.nix` to `~/.config/home-manager/flake.nix`.
+
The old location will continue to work but using it will trigger a warning message.
We changed the default configuration location to avoid confusion about
which files belong to Home Manager and which belong to Nixpkgs.
* The `home-manager` tool now offers an `init` command.
This command can be used to generate an initial Home Manager configuration,
and optionally also activate it.
The recommended installation method for a standalone Home Manager setup
with Nix flakes uses this new command.
The standard installation method remains the same but uses the new command internally.
See <<sec-flakes-standalone>> for more.
* When using <<opt-programs.fish.enable>>, the setup code
for <<opt-home.sessionVariables>> is now translated
with https://github.com/bouk/babelfish[babelfish].
This should result in significantly faster shell startup times
but could theoretically break
if you have very complex bash expressions in a session variable.
Please report any issues you experience.
[[sec-release-23.05-state-version-changes]]
=== State Version Changes
The state version in this release includes the changes below.
These changes are only active if the `home.stateVersion` option is set to "23.05" or later.
* The options
+
--
- <<opt-xsession.windowManager.i3.config.window.titlebar>>
- <<opt-xsession.windowManager.i3.config.floating.titlebar>>
- <<opt-wayland.windowManager.sway.config.window.titlebar>>
- <<opt-wayland.windowManager.sway.config.floating.titlebar>>
--
+
now default to `true` which is consistent with the default values for
those options used by `i3` and `sway`.
