fish completion: pipe straight to Python (#1076)

Browse Source 
In https://github.com/fish-shell/fish-shell/issues/10599, a user of an older version of fish has run into an issue with the fastfetch completion requiring a relatively new version.

Rewrite the (really quite clever) embedded Python into a straight pipe, dropping the string transformation entirely. Does require some escaping of quotes to support Python < 3.12.
