Subject: [PATCH] Ensure font features are applied to styled text (#44219)

- Replace `gpui::styled::Styled.font_family()` calls with
`gpui::styled::Styled.font()` when laying out inline diagnostics and
inline blame, to ensure that the font's features are also used, and
not just the font feature.
- Update both `editor::hover_popover::hover_markdown_style` and
`editor::hover_popover::diagnostics_markdown_style` to ensure that
both the UI and Buffer font features are used in both markdown and
diagnostics popover.

Closes #44209

Release Notes:

- Fixed font feature application for inline git blame, inline
diagnostics, markdown popovers and diagnostics popovers
