docs(release): drop fixed items from the alpha known-issues list (#21)

The HUD weapon/ammo-type icon (D187, PR #19) and blank briefing objective
text (D178, cd1ed574) are both fixed and on main. Remove them from the
release-notes and bundled-README known-issues blurbs so a v0.1.0 tag ships
an accurate list. Black sky and the front-end 3D models (Nintendo logo,
MISSION COMPLETE / mode-select) are still open and stay listed.
