[TEP-0100] Update deprecations table

With tektoncd#4739 merged and the v0.35.0 release coming up, it's time to update the deprecations table.
The plan is to switch the default value for `embedded-status` to `minimal` 9 months after the
release of v0.35.0, and then remove the `full` and `both` values in the following release. I
opted to use the date for changing the default as the "earliest date of removal" here.
