Release Strategy page is missing EOL date for 3.3

[alext-w]

Not sure if that's intentional or not, but I can't seem to find the EOL date for the recently released 3.3 branch. Checked the mail list announcement, NEWS/Changelog, and of course the authoritative Release Strategy page.

I'd be grateful for clarification on the support timelines for that branch and a page fix as appropriate.

v3.3 EOL date must be added to:
