When running under Fish shell it shows the shell as Bash, if bash

[mateowoetam]

I don't know how the program does this but when I run the following command the following command it runs properly except for the shell display:

brrtfetch -width 30 -height 30 -fps 10 /etc/nixos/ascii.gif

result:

fish is not configured as the user shell but it is the shell I've setup in alacritty to use, other fetchers like fastfetch and hyfetch detect the active shell correctly
expected result:

also it seems the text alignment is wonky whne you stop the command and it prints out the static version because the text is not aligned.

I am aware, I'm completely reworking brrtfetch. This bug will probably be fixed in the next version. That one should have full shell support. Might also add an option so users can specify the path to their preferred shell in case auto shell detection should fail for some edge cases. Some really cool stuff is coming soon :)

Also thinking about working with a brrtfetch.conf so people can more easily share configs and put them in their dotfiles. And then maybe make it so that flags can override specific parts of the config.

Thank you for being so engaged in this project btw!
