fish-shell: update to 3.4.0.
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **YES**

If you use an older Fish version as your shell and update to 3.4.0, you'll get the following (I believe harmless) error after the upgrade command finishes running and in some other instances:
```
/usr/share/fish/functions/fish_title.fish (line 7): $(...) is not supported. In fish, please use '(prompt_hostname)'.
        and set ssh "[$(prompt_hostname | string sub -l 10)]"
                      ^
from sourcing file /usr/share/fish/functions/fish_title.fish
in command substitution
source: Error while reading file “/usr/share/fish/functions/fish_title.fish”
```

Am I supposed to handle that somehow?
