feat(content/en): revert added dates to Wix 'coming soon' phrasing

Editorial choice #4 (concretized placeholders): Wix commits to no
dates; restore its wording:
- concept hero: 'Opening soon !:' + 'See all events here.' (was 'Opening Fall 2026:')
- events lede: 'coming soon !' (was 'in fall 2026!')
- long-stays teaser: 'coming soon' + 'See what's on here.' (dropped spring 2026/2027)
- reservations opening: 'Coming soon' (was 'Fall 2026')
