main/postmarketos-base-ui-gnome: remove epiphany user agent override

Our epiphany got blocked by https://gitlab.gnome.org/ due to their new
AI scraping protection. We used a older User-agent that is not
regocnized by their protection and blocked us with "Access Denied.".

Nowadays Epiphany uses a dynamic user agent by default depending on the
chassis reported by systemd-hostnamed (e.g. mobile or desktop).

Fixes: 2722f6cac5 ("main/postmarketos-ui-{gnome,phosh}: less revealing epiphany user-agent (MR 1402)")
